One who restrains his senses, keeping them under full control, and fixes his consciousness upon Me, is known as a man of steady intelligence.
That the highest conception of yoga perfection is Kṛṣṇa consciousness is clearly explained in this verse. And unless one is Kṛṣṇa conscious it is not at all possible to control the senses. As cited above, the great sage Durvāsā Muni picked a quarrel with MahārājaAmbarīṣa, and Durvāsā Muni unnecessarily became angry out of pride and therefore could not check his senses. On the other hand, the king, although not as powerful a yogī as the sage, but a devotee of the Lord, silently tolerated all the sage's injustices and thereby emerged victorious. The king was able to control his senses because of the following qualifications, as mentioned in the Śrīmad-Bhāgavatam (9.4.18-20):
sa vai manaḥ kṛṣṇa-padāravindayor
vacāṁsi vaikuṇṭha-guṇānuvarṇane
karau harer mandira-mārjanādiṣu
śrutiṁ cakārācyuta-sat-kathodaye
mukunda-liṅgālaya-darśane dṛśau
tad-bhṛtya-gātra-sparśe 'ṅga-saṅgamam
ghrāṇaṁ ca tat-pāda-saroja-saurabhe
śrīmat-tulasyā rasanāṁ tad-arpite
pādau hareḥ kṣetra-padānusarpaṇe
śiro hṛṣīkeśa-padābhivandane
kāmaṁ ca dāsye na tu kāma-kāmyayā
yathottama-śloka-janāśrayā ratiḥ
"King Ambarīṣa fixed his mind on the lotus feet of Lord Kṛṣṇa, engaged his words in describing the abode of the Lord, his hands in cleansing the temple of the Lord, his ears in hearing the pastimes of the Lord, his eyes in seeing the form of the Lord, his body in touching the body of the devotee, his nostrils in smelling the flavor of the flowers offered to the lotus feet of the Lord, his tongue in tasting the tulasī leaves offered to Him, his legs in traveling to the holy place where His temple is situated, his head in offering obeisances unto the Lord, and his desires in fulfilling the desires of the Lord... and all these qualifications made him fit to become a mat-para devotee of the Lord."
The word mat-para is most significant in this connection. How one can become mat-para is described in the life of Mahārāja Ambarīṣa. Śrīla Baladeva Vidyābhūṣaṇa, a great scholar and ācārya in the line of the mat-para, remarks, mad-bhakti-prabhāvena sarvendriya-vijaya-pūrvikā svātma-dṛṣṭiḥ sulabheti bhāvaḥ. "The senses can be completely controlled only by the strength of devotional service to Kṛṣṇa." Also, the example of fire is sometimes given: "As a blazing fire burns everything within a room, Lord Viṣṇu, situated in the heart of the yogī, burns up all kinds of impurities." The Yoga-sūtra also prescribes meditation on Viṣṇu, and not meditation on the void. The so-called yogīs who meditate on something other than the Viṣṇu form simply waste their time in a vain search after some phantasmagoria.
We have to be Kṛṣṇa conscious—devoted to the Personality of Godhead. This is the aim of the real yoga.
(Bhagavad-Gita------2:61------translation and purport).

"King Ambarīṣa first of all engaged his mind on the lotus feet of Lord Kṛṣṇa; then, one after another, he engaged his words in describing the transcendental qualities of the Lord, his hands in mopping the temple of the Lord, his ears in hearing of the activities of the Lord, his eyes in seeing the transcendental forms of the Lord, his body in touching the bodies of the devotees, his sense of smell in smelling the scents of the lotus flowers offered to the Lord, his tongue in tasting the tulasī leaf offered at the lotus feet of the Lord, his legs in going to places of pilgrimage and the temple of the Lord, his head in offering obeisances unto the Lord, and his desires in executing the mission of the Lord. All these transcendental activities are quite befitting a pure devotee."
(Bhagavad-Gita------6:18------ purport).

In the Padma Purāṇa, it is mentioned that Gautama Muni advised Mahārāja Ambarīṣa to hear regularly Śrīmad-Bhāgavatam as it was recited by Śukadeva Gosvāmī, and herein it is confirmed that Mahārāja Ambarīṣa heard Śrīmad-Bhāgavatam from the very beginning to the end, as it was spoken by Śukadeva Gosvāmī. One who is actually interested in the Bhāgavatam, therefore, must not play with it by reading or hearing a portion from here and a portion from there; one must follow in the footsteps of great kings like Mahārāja Ambarīṣaor Mahārāja Parīkṣit and hear it from a bona fide representative of Śukadeva Gosvāmī.
(Srimad Bhagavatam------2:1:10------purport).

The yogeśvara, or the master of mystic powers, can exhibit eight kinds of wonders of perfection by becoming smaller than the atom or lighter than a feather, getting anything and everything he desires, going anywhere and everywhere he likes, creating even a planet in the sky, etc. There are many yogeśvaras having different proficiencies in these wonderful powers, and the topmost of all of them is Lord Śiva. Lord Śiva is the greatest yogī, and he can perform such wonderful things, far beyond the ordinary living beings. The devotees of the Lord, the Supreme Personality of Godhead, do not directly practice the process of mystic powers, but, by the grace of the Lord, His devotee can defeat even a great yogeśvara like Durvāsā Muni, who picked a quarrel with Mahārāja Ambarīṣa and wanted to show the wonderful achievements of his mystic powers. Mahārāja Ambarīṣa was a pure devotee of the Lord, and thus without any effort on his part the Lord saved him from the wrath of Yogeśvara Durvāsā Muni, and the latter was obliged to beg pardon from the King.
(Srimad Bhagavatam------2:8:20------purport).

Here the words mano mayy arpitam, which mean "the mind being fixed on Me," are significant. One should fix his mind on the lotus feet of Kṛṣṇa or His incarnation. To be fixed steadily in that freedom is the way of liberation. Ambarīṣa Mahārāja is an example. He fixed his mind on the lotus feet of the Lord, he spoke only on the pastimes of the Lord, he smelled only the flowers and tulasī offered to the Lord, he walked only to the temple of the Lord, he engaged his hands in cleansing the temple, he engaged his tongue in tasting the foodstuff offered to the Lord, and he engaged his ears for hearing the great pastimes of the Lord. In that way all his senses were engaged.
(Srimad Bhagavatam------3:25:44------purport).

In the life of Mahārāja Ambarīṣa, we find that the great Mahārāja first engaged his mind on the lotus feet of Kṛṣṇa. In this way his intelligence became purified. Mahārāja Ambarīṣa also used his other senses in the service of the Lord. He engaged his eyes in seeing the Deity in the temple nicely decorated with flowers. He engaged his sense of smell by smelling the flowers, and he engaged his legs by walking to the temple. His hands were engaged in cleansing the temple, and his ears were engaged in hearing about Kṛṣṇa. His tongue was engaged in two ways: in speaking about Kṛṣṇa and in tasting prasāda offered to the Deity. Materialistic persons, who are under the full control of material intelligence, cannot perform all these activities. Thus, consciously or unconsciously, they become entangled by the dictations of material intelligence.
(Srimad Bhagavatam------3:25:57-61------purport).

One's pure intelligence, or pure Kṛṣṇa consciousness, becomes polluted by material activities. Pure consciousness can be revived by the process of sacrifice, charity, pious activities, etc., but when one pollutes his Kṛṣṇa consciousness by offending a brāhmaṇa or a Vaiṣṇava, it is very difficult to revive. Śrī Caitanya Mahāprabhu has described the vaiṣṇava-aparādha, or offense to a Vaiṣṇava, as "the mad elephant offense." One should be very careful not to offend a Vaiṣṇava or a brāhmaṇa. Even the great yogī Durvāsā was harassed by the Sudarśana cakra when he offended the Vaiṣṇava Mahārāja Ambarīṣa, who was neither a brāhmaṇa nor a sannyāsī but an ordinary householder. Mahārāja Ambarīṣa was a Vaiṣṇava, and consequently Durvāsā Muni was chastised.
The conclusion is that if Kṛṣṇa consciousness is covered by material sins, one can eliminate the sins simply by chanting the Hare Kṛṣṇa mantra, but if one pollutes his Kṛṣṇa consciousness by offending a brāhmaṇa or a Vaiṣṇava, one cannot revive it until one properly atones for the sin by pleasing the offended Vaiṣṇava or brāhmaṇa. This was the course that Durvāsā Muni had to follow, for he surrendered unto Mahārāja Ambarīṣa. A vaiṣṇava-aparādha cannot be atoned for by any means other than by begging the pardon of the offended Vaiṣṇava.
(Srimad Bhagavatam------4:26:24------purport).

Once Mahārāja Ambarīṣa was worshiping the Supreme Personality of Godhead in Vṛndāvana, observing the vow of Dvādaśī. On Dvādaśī, the day after Ekādaśī, when he was about to break his Ekādaśī fast, the great mystic yogī Durvāsā appeared in his house and became his guest. King Ambarīṣa respectfully received Durvāsā Muni, and Durvāsā Muni, after accepting his invitation to eat there, went to bathe in the Yamunā River at noontime. Because he was absorbed in samādhi, he did not come back very soon. Mahārāja Ambarīṣa, however, upon seeing that the time to break the fast was passing, drank a little water, in accordance with the advice of learned brāhmaṇas, just to observe the formality of breaking the fast. By mystic power, Durvāsā Muni could understand that this had happened, and he was very angry. When he returned he began to chastise Mahārāja Ambarīṣa, but he was not satisfied, and finally he created from his hair a demon appearing like the fire of death. The Supreme Personality of Godhead, however, is always the protector of His devotee, and to protect MahārājaAmbarīṣa, He sent His disc, the Sudarśana cakra, which immediately vanquished the fiery demon and then pursued Durvāsā, who was so envious of Mahārāja Ambarīṣa. Durvāsā fled to Brahmaloka, Śivaloka and all the other higher planets, but he could not protect himself from the wrath of the Sudarśana cakra. Finally he went to the spiritual world and surrendered to Lord Nārāyaṇa, but Lord Nārāyaṇa could not excuse a person who had offended a Vaiṣṇava. To be excused from such an offense, one must submit to the Vaiṣṇava whom he has offended. There is no other way to be excused. Thus Lord Nārāyaṇa advised Durvāsā to return to Mahārāja Ambarīṣa and beg his pardon.
(Srimad Bhagavatam------9:4:------summary).

Mahārāja Ambarīṣa always engaged his mind in meditating upon the lotus feet of Kṛṣṇa, his words in describing the glories of the Lord, his hands in cleansing the Lord's temple, and his ears in hearing the words spoken by Kṛṣṇa or about Kṛṣṇa. He engaged his eyes in seeing the Deity of Kṛṣṇa, Kṛṣṇa's temples and Kṛṣṇa's places like Mathurā and Vṛndāvana, he engaged his sense of touch in touching the bodies of the Lord's devotees, he engaged his sense of smell in smelling the fragrance of tulasī offered to the Lord, and he engaged his tongue in tasting the Lord's prasāda. He engaged his legs in walking to the holy places and temples of the Lord, his head in bowing down before the Lord, and all his desires in serving the Lord, twenty-four hours a day. Indeed, Mahārāja Ambarīṣa never desired anything for his own sense gratification. He engaged all his senses in devotional service, in various engagements related to the Lord. This is the way to increase attachment for the Lord and be completely free from all material desires.
(Srimad Bhagavatam------9:4:18-20------translation).

In performing his prescribed duties as king, Mahārāja Ambarīṣa always offered the results of his royal activities to the Supreme Personality of Godhead, Kṛṣṇa, who is the enjoyer of everything and is beyond the perception of material senses. He certainly took advice from brāhmaṇas who were faithful devotees of the Lord, and thus he ruled the planet earth without difficulty.
As stated in Bhagavad-gītā (5.29):
bhoktāraṁ yajña-tapasāṁ
sarva-loka-maheśvaram
suhṛdaṁ sarva-bhūtānāṁ
jñātvā māṁ śāntim ṛcchati
People are very much anxious to live in peace and prosperity in this material world, and here in Bhagavad-gītā the peace formula is given personally by the Supreme Personality of Godhead: everyone should understand that Kṛṣṇa, the Supreme Personality of Godhead, is the ultimate proprietor of all the planets and is therefore the enjoyer of all activities, political, social, cultural, religious, economic and so on. The Lord has given perfect advice in Bhagavad-gītā, and Ambarīṣa Mahārāja, as the ideal executive head, ruled the entire world as a Vaiṣṇava, taking advice from Vaiṣṇava brāhmaṇas. The śāstras enjoin that even though a brāhmaṇa may be well versed in the occupational brahminical duties and may be very learned in Vedic knowledge, he cannot give advice as a guru until he is a Vaiṣṇava.
ṣaṭ-karma-nipuṇo vipro
mantra-tantra-viśāradaḥ
avaiṣṇavo gurur na syād
vaiṣṇavaḥ śva-paco guruḥ
Therefore, as indicated here by the words tan-niṣṭha-viprābhihitaḥ, Mahārāja Ambarīṣa took advice from brāhmaṇas who were pure devotees of the Lord, for ordinary brāhmaṇas who are merely learned scholars or experts in performing ritualistic ceremonies are not competent to give advice.

(Srimad Bhagavatam------9:4:21------translation and purport).

Śrīla Viśvanātha Cakravartī Ṭhākura has diverted the entire meaning of this verse as spoken by Durvāsā Muni. Durvāsā Muni used the word nṛ-śaṁsasya to indicate that the King was cruel, but Viśvanātha Cakravartī Ṭhākura interprets it to mean that the King's character was glorified by all the local people. He says that the word nṛ means "by all the local people" and that śaṁsasya means "of he (Ambarīṣa) whose character was glorified." Similarly, one who is very rich becomes mad because of his wealth and is therefore called śriyā-unmattasya, but Śrīla Viśvanātha Cakravartī Ṭhākura interprets these words to mean that although Mahārāja Ambarīṣa was such an opulent king, he was not mad after money, for he had already surpassed the madness of material opulence. Similarly, the word īśa-māninaḥ is interpreted to mean that he was so respectful to the Supreme Personality of Godhead that he did not transgress the laws for observing Ekādaśī-pāraṇa, despite the thinking of Durvāsā Muni, for he only took water. In this way, Śrīla Viśvanātha Cakravartī Ṭhākura has supported Ambarīṣa Mahārāja and all his activities.
(Srimad Bhagavatam------9:4:44------purport).

The Supreme Personality of Godhead is worshiped by the words brahmaṇya-devāya go-brāhmaṇa-hitāya ca. Thus He is the well-wisher of the brāhmaṇas. Durvāsā Muni was certainly a very great brāhmaṇa, but because he was a nondevotee, he could not sacrifice everything in devotional service. Great mystic yogīs are actually self-interested. The proof is that when Durvāsā Muni created a demon to kill Mahārāja Ambarīṣa, the King stayed fixed in his place, praying to the Supreme Personality of Godhead and depending solely and wholly on Him, whereas when Durvāsā Muni was chased by the Sudarśana cakra by the supreme will of the Lord, he was so perturbed that he fled all over the world and tried to take shelter in every nook and corner of the universe. At last, in fear of his life, he approached Lord Brahmā, Lord Śiva and ultimately the Supreme Personality of Godhead. He was so interested in his own body that he wanted to kill the body of a Vaiṣṇava. Therefore, he did not have very good intelligence, and how can an unintelligent person be delivered by the Supreme Personality of Godhead? The Lord certainly tries to give all protection to His devotees who have given up everything for the sake of serving Him.
(Srimad Bhagavatam------9:4:65------purport).

Since Durvāsā Muni wanted to chastise Mahārāja Ambarīṣa, it is to be understood that he wanted to give pain to the heart of the Supreme Personality of Godhead, for the Lord says, sādhavo hṛdayaṁ mahyam: "The pure devotee is always within the core of My heart." The Lord's feelings are like those of a father, who feels pain when his child is in pain. Therefore, offenses at the lotus feet of a devotee are serious. Caitanya Mahāprabhu has very strongly recommended that one not commit any offense at the lotus feet of a devotee. Such offenses are compared to a mad elephant because when a mad elephant enters a garden it causes devastation. Therefore one should be extremely careful not to commit offenses at the lotus feet of a pure devotee. Actually Mahārāja Ambarīṣa was not at all at fault; Durvāsā Muni unnecessarily wanted to chastise him on flimsy grounds. Mahārāja Ambarīṣa wanted to complete the Ekādaśī-pāraṇa as part of devotional service to please the Supreme Personality of Godhead, and therefore he drank a little water. But although Durvāsā Muni was a great mystic brāhmaṇa, he did not know what is what. That is the difference between a pure devotee and a so-called learned scholar of Vedic knowledge.
(Srimad Bhagavatam------9:4:68------purport).

O brāhmaṇa, let Me now advise you for your own protection. Please hear from Me. By offending Mahārāja Ambarīṣa, you have acted with self-envy. Therefore you should go to him immediately, without a moment's delay. One's so-called prowess, when employed against the devotee, certainly harms he who employs it. Thus it is the subject, not the object, who is harmed.
A Vaiṣṇava is always an object of envy for nondevotees, even when the nondevotee happens to be his father. To give a practical example, Hiraṇyakaśipu was envious of Prahlāda Mahārāja, but this envy of the devotee was harmful to Hiraṇyakaśipu, not to Prahlāda. Every action taken by Hiraṇyakaśipu against his son Prahlāda Mahārāja was taken very seriously by the Supreme Personality of Godhead, and thus when Hiraṇyakaśipu was on the verge of killing Prahlāda, the Lord personally appeared and killed Hiraṇyakaśipu. Service to a Vaiṣṇava gradually accumulates and becomes an asset for the devotee. Similarly, harmful activities directed against the devotee gradually become the ultimate cause of the performer's falldown. Even such a great brāhmaṇa and mystic yogī as Durvāsā was in a most dangerous situation because of his offense at the lotus feet of Mahārāja Ambarīṣa, a pure devotee.
(Srimad Bhagavatam------9:4:69------translation and purport).

In this chapter we find Mahārāja Ambarīṣa offering prayers to the Sudarśana cakra and we find how the Sudarśana cakra became merciful to Durvāsā Muni.
By the order of the Supreme Personality of Godhead, Viṣṇu, Durvāsā Muni immediately went to Mahārāja Ambarīṣa and fell at his lotus feet. Mahārāja Ambarīṣa, being naturally very humble and meek, felt shy and ashamed because Durvāsā Muni had fallen at his feet, and thus he began to offer prayers to the Sudarśana cakra just to save Durvāsā. What is this Sudarśana cakra? The Sudarśana cakra is the glance of the Supreme Personality of Godhead by which He creates the entire material world. Sa aikṣata, sa asṛjata. This is the Vedic version. The Sudarśana cakra, which is the origin of creation and is most dear to the Lord, has thousands of spokes. This Sudarśana cakra is the killer of the prowess of all other weapons, the killer of darkness, and the manifester of the prowess of devotional service; it is the means of establishing religious principles, and it is the killer of all irreligious activities. Without his mercy, the universe cannot be maintained, and therefore the Sudarśana cakra is employed by the Supreme Personality of Godhead. When Mahārāja Ambarīṣa thus prayed that the Sudarśana cakra be merciful, the Sudarśana cakra, being appeased, refrained from killing Durvāsā Muni, who thus achieved the Sudarśana cakra's mercy. Durvāsā Muni thus learned to give up the nasty idea of considering a Vaiṣṇava an ordinary person (vaiṣṇave jāti-buddhi). Mahārāja Ambarīṣa belonged to the kṣatriya group, and therefore Durvāsā Muni considered him lower than the brāhmaṇas and wanted to exercise brahminical power against him. By this incident, everyone should learn how to stop mischievous ideas of neglecting Vaiṣṇavas. After this incident, Mahārāja Ambarīṣa gave Durvāsā Muni sumptuous food to eat, and then the King, who had been standing in the same place for one year without eating anything, also took prasāda. Mahārāja Ambarīṣa later divided his property among his sons and went to the bank of the Mānasa-sarovara to execute devotional meditation.
(Srimad Bhagavatam------9:5:------summary).

After one year, when Durvāsā Muni had returned, King Ambarīṣa sumptuously fed him all varieties of pure food, and then he himself also ate. When the King saw that the brāhmaṇa Durvāsā had been released from the great danger of being burned, he could understand that by the grace of the Lord he himself was also powerful, but he did not take any credit, for everything had been done by the Lord.
A devotee like Mahārāja Ambarīṣa is certainly always busy in many activities. Of course, this material world is full of dangers that one has to meet, but a devotee, because of his full dependence on the Supreme Personality of Godhead, is never disturbed. The vivid example is Mahārāja Ambarīṣa. He was the emperor of the entire world and had many duties to perform, and in the course of these duties there were many disturbances created by persons like Durvāsā Muni, but the King tolerated everything, patiently depending fully on the mercy of the Lord. The Lord, however, is situated in everyone's heart (sarvasya cāhaṁ hṛdi sanniviṣṭaḥ (B.G.15:15), and He manages things as He desires. Thus although Mahārāja Ambarīṣa was faced with many disturbances, the Lord, being merciful to him, managed things so nicely that in the end Durvāsā Muni and Mahārāja Ambarīṣa became great friends and parted cordially on the basis of bhakti-yoga. After all, Durvāsā Muni was convinced of the power of bhakti-yoga, although he himself was a great mystic yogī. Therefore, as stated by Lord Kṛṣṇa in Bhagavad-gītā (6.47):
yoginām api sarveṣāṁ
mad-gatenāntarātmanā
śraddhāvān bhajate yo māṁ
sa me yuktatamo mataḥ
"Of all yogīs, he who always abides in Me with great faith, worshiping Me in transcendental loving service, is most intimately united with Me in yoga and is the highest of all." Thus it is a fact that a devotee is the topmost yogī, as proved in the dealings of Mahārāja Ambarīṣa with Durvāsā Muni.
(Srimad Bhagavatam------9:5:24------translation and purport).

Śrīla Śukadeva Gosvāmī continued: Thereafter, because of his advanced position in devotional life, Mahārāja Ambarīṣa, who no longer desired to live with material things, retired from active family life. He divided his property among his sons, who were equally as qualified, and he himself took the order of vānaprastha and went to the forest to concentrate his mind fully upon Lord Vāsudeva.
As a pure devotee, Mahārāja Ambarīṣa was liberated in any condition of life because, as enunciated by Śrīla Rūpa Gosvāmī, a devotee is always liberated.
īhā yasya harer dāsye
karmaṇā manasā girā
nikhilāsv apy avasthāsu
jīvan-muktaḥ sa ucyate
In Bhakti-rasāmṛta-sindhu, Śrīla Rūpa Gosvāmī thus instructs that if one's only desire is service to the Lord, he is liberated in any condition of life. Mahārāja Ambarīṣa was undoubtedly liberated in any condition, but as an ideal king he accepted the vānaprastha order of retirement from family life. It is essential for one to renounce family responsibilities and fully concentrate on the lotus feet of Vāsudeva. Therefore Mahārāja Ambarīṣa divided the kingdom among his sons and retired from family life.
(Srimad Bhagavatam------9:5:26------translation and purport).
