Tat-puruṣa refers to a preacher of Kṛṣṇa consciousness, such as the spiritual master. Śrīla Narottama dāsa Ṭhākura has said, chāḍiyā vaiṣṇava-sevā nistāra pāyeche kebā: "Without serving a bona fide spiritual master, an ideal Vaiṣṇava, who can be delivered from the clutches of māyā?" This idea is also expressed in many other places. Śrīmad-Bhāgavatam (5.5.2) says, mahat-sevāṁ dvāram āhur vimukteḥ: if one desires liberation from the clutches of māyā, one must associate with a pure devotee mahātmā. A mahātmā is one who engages twenty-four hours daily in the loving service of the Lord.
(Srimad Bhagavatam----6:1:16----purport).

Mahājano yena gataḥ sa panthāḥ: (CC.2:17:186) one must follow the path of the mahājanas. The mahājanas are those who have taken to the path of devotional service (suśīlāḥ sādhavo yatra nārāyaṇa-parāyaṇāḥ), for these great personalities are the perfect persons. As stated in Śrīmad-Bhāgavatam (5.18.12):
yasyāsti bhaktir bhagavaty akiñcanā
sarvair guṇais tatra samāsate surāḥ
"One who has unflinching devotion to the Personality of Godhead has all the good qualities of the demigods." The less intelligent, however, misunderstand the bhakti path and therefore allege that it is for one who cannot execute ritualistic ceremonies or speculate. As confirmed here by the word sadhrīcīnaḥ, bhakti is the path that is appropriate, not the paths of karma-kāṇḍa and jñāna-kāṇḍa. Māyāvādīs may be suśīlāḥ sādhavaḥ (well-behaved saintly persons), but there is nevertheless some doubt about whether they are actually making progress, for they have not accepted the path of bhakti. On the other hand, those who follow the path of the ācāryas are suśīlāḥ and sādhavaḥ, but furthermore their path is akuto-bhaya, which means free from fear. One should fearlessly follow the twelve mahājanas and their line of disciplic succession and thus be liberated from the clutches of māyā.
(Srimad Bhagavatam----6:1:17----purport).

According to his association with the material modes of nature—goodness, passion and ignorance—a living entity gets a particular type of body. The example of one who associates with the mode of goodness is a qualified brāhmaṇa. Such a brāhmaṇa knows past, present and future because he consults the Vedic literature and sees through the eyes of śāstra (śāstra-cakṣuḥ). He can understand what his past life was, why be is in the present body, and how he can obtain liberation from the clutches of māyā and not accept another material body. This is all possible when one is situated in the mode of goodness. Generally, however, the living entities are engrossed in the modes of passion and ignorance.
(Srimad Bhagavatam----6:1:49----purport).

This should be the standard of determination for all Kṛṣṇa conscious persons. A Kṛṣṇa conscious person should free himself from the clutches of māyā, and he should also be compassionate to all others suffering in those clutches. The activities of the Kṛṣṇa consciousness movement are meant not only for oneself but for others also. This is the perfection of Kṛṣṇa consciousness. One who is interested in his own salvation is not as advanced in Kṛṣṇa consciousness as one who feels compassion for others and who therefore propagates the Kṛṣṇa consciousness movement. Such an advanced devotee will never fall down, for Kṛṣṇa will give him special protection. That is the sum and substance of the Kṛṣṇa consciousness movement. Everyone is like a play toy in the hands of the illusory energy and is acting as she moves him. One should come to Kṛṣṇa consciousness to release oneself and also to release others.
(Srimad Bhagavatam----6:2:36-37----purport).

This power of chanting the holy name was proved by the liberation of Ajāmila. When Ajāmila chanted the holy name of Nārāyaṇa, he did not precisely remember the Supreme Lord; instead, he remembered his own son. At the time of death, Ajāmila certainly was not very clean; indeed, he was famous as a great sinner. Furthermore, one's physiological condition is completely disturbed at the time of death, and in such an awkward condition it would certainly have been very difficult for Ajāmila to have chanted clearly. Nevertheless, Ajāmila achieved liberation simply by chanting the holy name of the Lord. Therefore, what is to be said of those who are not sinful like Ajāmila? It is to be concluded that with a strong vow one should chant the holy name of the Lord—Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare—for thus one will certainly be delivered from theclutches of māyā by the grace of Kṛṣṇa.
(Srimad Bhagavatam----6:3:24----purport).

The Haryaśvas, the sons of Prajāpati Dakṣa, could immediately understand the purport of Nārada's instructions. Our Kṛṣṇa consciousness movement is especially meant for such enlightenment. We are trying to enlighten humanity so that people may come to the understanding that they should work hard in tapasya for self-realization and freedom from the continuous bondage of birth, death, old age and disease in one body after another. Māyā, however, is very strong; she is expert in putting impediments in the way of this understanding. Therefore sometimes one comes to the Kṛṣṇa consciousness movement but again falls into the clutches of māyā, not understanding the importance of this movement.
(Srimad Bhagavatam----6:5:11----purport).

As confirmed in the Brahma-saṁhitā, all these forms of the Supreme Personality of Godhead are advaita, nondifferent, and they are also acyuta, infallible; they do not fall down like the conditioned souls. The ordinary living entity is prone to falling into the clutches of māyā, but the Supreme Lord in His different incarnations and forms is acyuta, infallible. Therefore His body is different from the material body possessed by the conditioned soul.
(Srimad Bhagavatam----6:16:18-19----purport).

The spiritual master, the servant of God, is engaged in the most confidential service of the Lord, namely delivering all the conditioned souls from the clutches of māyā, in which one thinks, "This person is my enemy, and that one is my friend." Actually the Supreme Personality of Godhead is the friend of all living entities, and all living entities are eternal servants of the Supreme Lord. Oneness is possible through this understanding, not through artificially thinking that every one of us is God or equal to God. The true understanding is that God is the supreme master and that all of us are servants of the Supreme Lord and are therefore on the same platform. This had already been taught to Prahlāda Mahārāja by his spiritual master, Nārada, but Prahlāda was nonetheless surprised by how a bewildered soul thinks one person his enemy and another his friend.
(Srimad Bhagavatam----7:5:11----purport).

As long as one adheres to the philosophy of duality, thinking one person a friend and another an enemy, he should be understood to be in the clutches of māyā. The Māyāvādī philosopher who thinks that all living entities are God and are therefore one is also mistaken. No one is equal to God. The servant cannot be equal to the master. According to the Vaiṣṇava philosophy, the master is one, and the servants are also one, but the distinction between the master and servant must continue even in the liberated stage. In the conditioned stage we think that some living beings are our friends whereas others are enemies, and thus we are in duality. In the liberated stage, however, the conception is that God is the master and that all living entities, being servants of God, are one.
(Srimad Bhagavatam----7:5:11----purport).

One cannot understand Kṛṣṇa unless one is graced by the Supreme Personality of Godhead. Only one who has surrendered to a pure devotee of Kṛṣṇa and taken the dust of his lotus feet can understand Kṛṣṇa. First one must understand how to get out of the clutches of māyā. The only means is to become Kṛṣṇa conscious. And to become Kṛṣṇa conscious very easily, one must take shelter of a realized soul—a mahat, or mahātmā—whose only interest is to engage in the service of the Supreme Lord.
(Srimad Bhagavatam----7:5:32----purport).

Any person engaged in the service of the Lord through the instructions of a bona fide spiritual master is immediately liberated, and being free from the clutches of māyā, he is relieved of all ignorance and material desires. The duty of everyone is to take shelter of the Supreme Lord and thus become free from all material desires. Regardless of the material condition in which one is situated, one can achieve this perfection. Devotional service is not dependent on the material activities of austerity, penance, mystic yoga or piety. Even without such assets, one can achieve devotional service through the mercy of a pure devotee.
(Srimad Bhagavatam-----7:7--summary).

One must find some time for hearing Śrīmad-Bhāgavatam and Bhagavad-gītā. This is Vedic culture. One should work eight hours at the most to earn his livelihood, and either in the afternoon or in the evening a householder should associate with devotees to hear about the incarnations of Kṛṣṇa and His activities and thus be gradually liberated from theclutches of māyā. However, instead of finding time to hear about Kṛṣṇa, the householders, after working hard in offices and factories, find time to go to a restaurant or a club where instead of hearing about Kṛṣṇa and His activities they are very much pleased to hear about the political activities of demons and nondevotees and to enjoy sex, wine, women and meat and in this way waste their time. This is not gṛhastha life, but demoniac life. The Kṛṣṇa consciousness movement, however, with its centers all over the world, gives such fallen and condemned persons an opportunity to hear about Kṛṣṇa.
(Srimad Bhagavatam----7:14:3-4----purport).

When one misuses the gift of the human form by unnecessarily indulging in the animal propensities of eating, sleeping, mating and defending and does not try to get out of the clutches of māyā, which subjects one to repeated birth, death, old age and disease, one is again punished by being forced to descend to the lower species and undergo evolution according to the laws of nature. prakṛteḥ kriyamāṇāni guṇaiḥ karmāṇi sarvaśaḥ (B.G.3:27). Being completely under the grip of material nature, the living entity must evolve again from the lower species to the higher species until he at last returns to human life and gets the chance to be freed from the material clutches. A wise man, however, learns from the śāstras and guru that we living entities are all eternal but are put into troublesome conditions because of associating with different modes under the laws of material nature. He therefore concludes that in the human form of life he should not endeavor for unnecessary necessities, but should live a very simple life, just maintaining body and soul together.
(Srimad Bhagavatam----7:14:5----purport).

The perfection of knowledge is certainly to become transcendentally situated (brahma-bhūta (S.B.4:30:20). As the Lord says in Bhagavad-gītā (18.54):
brahma-bhūtaḥ prasannātmā
na śocati na kāṅkṣati
samaḥ sarveṣu bhūteṣu
mad-bhaktiṁ labhate parām
"One who is transcendentally situated at once realizes the Supreme Brahman and becomes fully joyful. He never laments nor desires to have anything; he is equally disposed toward all living entities. In that state he attains pure devotional service." Simply by cultivating knowledge as the impersonalists do, one cannot get out of the clutches of māyā. One must attain the platform of bhakti.
(Srimad Bhagavatam----7:14:45----purport).

"The living entity under the clutches of māyā wants to enjoy this material world, but unless You give him directions and remind him, he cannot make progress in pursuing his shadowy objective in life. The conditioned soul wrongly progresses toward the wrong objective, life after life, and he is reminded of that objective by You. In one life the conditioned soul desires to progress toward a certain objective, but after his body changes, he forgets everything. Nonetheless, my Lord, because he wanted to enjoy something of this world, You remind him of this in his next birth. Mattaḥ smṛtir jñānam apohanaṁ ca (B.G.15:15). Because the conditioned soul wants to forget You, by Your grace You give him opportunities, life after life, by which he can almost perpetually forget You. Therefore You are eternally the director of the conditioned souls."
(Srimad Bhagavatam----8:3:14----purport).

At the end of every catur-yuga, consisting of Satya-yuga, Dvāpara-yuga, Tretā-yuga and Kali-yuga, the sages, acting under the orders of the Supreme Personality of Godhead, distribute the Vedic knowledge and thus reinstate eternal religious principles. Manu's duty is to reestablish the system of religion. Manu's sons execute Manu's orders, and thus the entire universe is maintained by Manu and his descendants. The Indras are various rulers of the heavenly planets. Assisted by the demigods, they rule the three worlds. The Supreme Personality of Godhead also appears as incarnations in different yugas. He appears as Sanaka, Sanātana, Yājñavalkya, Dattātreya and others, and thus He gives instructions in spiritual knowledge, prescribed duties, principles of mystic yoga, and so on. As Marīci and others, He creates progeny; as the king, He punishes the miscreants; and in the form of time, He annihilates the creation. One may argue, "If the all-powerful Supreme Personality of Godhead can do anything simply by His will, why has He arranged for so many personalities to manage?" How and why He does this cannot be understood by those who are under the clutches of māyā.
(Srimad Bhagavatam----8:14--summary).

Mahārāja Satyavrata, however, knew the goal of life. He knew the Supreme Personality of Godhead, and therefore he accepted the Lord as his guru. Either the Supreme Lord or His representative can become guru. The Lord says, mām eva ye prapadyante māyām etāṁ taranti te: (B.G.7:14) "One can get relief from the clutches of māyā as soon as he surrenders unto Me." Therefore it is the guru's business to instruct his disciple to surrender to the Supreme Personality of Godhead if he wants relief from the material clutches. This is the symptom of the guru. This same principle was instructed by Śrī Caitanya Mahāprabhu: yāre dekha, tāre kaha 'kṛṣṇa'-upadeśa (CC.2:7:128). In other words, one is advised not to accept a guru who does not follow the path of instruction given by Lord Kṛṣṇa.
(Srimad Bhagavatam----8:24:50----purport).

In Bhagavad-gītā (9.21) it is said, kṣīṇe puṇye martya-lokaṁ viśanti: "When the results of their pious activities are exhausted, those who have enjoyed in the heavenly planets fall again to earth." The fruitive activities of this material world are such that whether one acts piously or impiously one must remain within the material world according to different conditions, for neither pious nor impious actions can relieve one from māyā's clutches of repeated birth and death.
(Srimad Bhagavatam----9:10:23----purport).

The word bhūri-puṇyavad-arpitaiḥ is significant in this verse. These forms of Viṣṇu were worshiped by those who had performed pious activities (sukṛtibhiḥ) for many births and who were constantly engaged in devotional service (śravaṇaṁ kīrtanaṁ viṣṇoḥ (S.B.7:5:23). Bhakti, devotional service, is the engagement of those who have performed highly developed pious activities. The accumulation of pious activities has already been mentioned elsewhere in the Śrīmad-Bhāgavatam (10.12.11), where Śukadeva Gosvāmī says,
itthaṁ satāṁ brahma-sukhānubhūtyā
dāsyaṁ gatānāṁ para-daivatena
māyāśritānāṁ nara-dārakeṇa
sākaṁ vijahruḥ kṛta-puṇya-puñjāḥ
"Those who are engaged in self-realization, appreciating the Brahman effulgence of the Lord, and those engaged in devotional service, accepting the Supreme Personality of Godhead as master, as well as those who are under the clutches of māyā, thinking the Lord an ordinary person, cannot understand that certain exalted personalities—after accumulating volumes of pious activities—are now playing with the Lord in friendship as cowherd boys."
(Srimad Bhagavatam----10:13:49----purport).
