"Kṛṣṇa, who is known as Govinda, is the supreme controller. He has an eternal, blissful, spiritual body. He is the origin of all. He has no other origin, for He is the prime cause of all causes."
(Srimad Bhagavatam------6:1:41------purport).

Our dear Lord, O supreme controller, when You appear on earth, all the demons like Kaṁsa and Jarāsandha will be vanquished, and all good fortune will be ushered into the world. When You walk on the globe, Your lotus feet will impress on the ground the marks of Your soles, such as the flag, the trident and the thunderbolt. Thus You will grace both the earth and us on the heavenly planets who shall see those marks.
(Krsna Book).

Vāsudeva, or Lord Kṛṣṇa, the Absolute Personality of Godhead, is the supreme controller of everything, and as such He is feared by all others. There is no one in creation who is not afraid of the rage of the Almighty. Great asuras like Rāvaṇa, Hiraṇyakaśipu, Kaṁsa, and others who were very powerful living entities were all killed by the Personality of Godhead. And the almighty Vāsudeva has empowered His name with the powers of His personal Self. Everything directly related to Him is identical with Him. It is stated herein that the name of Kṛṣṇa is feared even by fear personified. This indicates that the name of Kṛṣṇa is nondifferent from Kṛṣṇa. Therefore, the name of Kṛṣṇa is as powerful as Lord Kṛṣṇa Himself. There is no difference at all. Anyone, therefore, can take advantage of the holy names of Lord Śrī Kṛṣṇa even in the midst of greatest dangers. The transcendental name of Kṛṣṇa, even though uttered unconsciously or by force of circumstances, can help one obtain freedom from the hurdle of birth and death.
(Srimad Bhagavatam------1:1:14------purport).

The unmarried gopīs used to prepare the deity of Goddess Durgā and worship it with candana pulp, garlands, incense, lamps and all kinds of presentations—fruits, grain and twigs of plants. After worshiping, it is the custom to pray for some benediction. The unmarried girls used to pray with great devotion to Goddess Kātyāyanī, addressing her as follows: "O supreme external energy of the Personality of Godhead, O supreme mystic power, O supreme controller of this material world, O goddess, please be kind to us and arrange for our marriage with the son of Nanda Mahārāja, Kṛṣṇa." The Vaiṣṇavas generally do not worship any demigods. Śrīla Narottama dāsa Ṭhākura has strictly forbidden all worship of the demigods for anyone who wants to advance in pure devotional service.
(Krsna Book).

If the Personality of Godhead did not possess both limited and unlimited energies, He could not be called omnipotent. Aṇor aṇīyān mahato mahīyān: "The Lord is smaller than the smallest and greater than the greatest." He is smaller than the smallest in the form of the living entities and greater than the greatest in His form of Kṛṣṇa. If there were no one to control, there would be no meaning to the conception of the supreme controller (īśvara), just as there is no meaning to a king without his subjects. If all the subjects became king, there would be no distinction between the king and an ordinary citizen. Thus for the Lord to be the supreme controller there must be a creation to control. The basic principle for the existence of the living entities is called cid-vilāsa, or spiritual pleasure. The omnipotent Lord displays His pleasure potency as the living entities. The Lord is described in the Vedānta-sūtra (1.1.12) as ānanda-mayo ’bhyāsāt. He is by nature the reservoir of all pleasures, and because He wants to enjoy pleasure, there must be energies to give Him pleasure or supply Him the impetus for pleasure. This is the perfect philosophical understanding of the Absolute Truth.
(Sri Caitanya Caritamrta------1:7:116-------purport).

The Supreme Personality of Godhead, Kṛṣṇa, thus advised the cowherd men to stop the Indra-yajña and begin the Govardhana-pūjā in order to chastise Indra, who was very much puffed up at being the supreme controller of the heavenly planets. The honest and simple cowherd men, headed by Nanda Mahārāja, accepted Kṛṣṇa's proposal and executed in detail everything He advised. They performed Govardhana worship and circumambulation of the hill. (Following the inauguration of Govardhana-pūjā, people in Vṛndāvana still dress nicely and assemble near Govardhana Hill to offer worship and circumambulate the hill, leading their cows all around.) According to the instruction of Lord Kṛṣṇa, Nanda Mahārāja and the cowherd men called in learned brāhmaṇas and began to worship Govardhana Hill by chanting Vedic hymns and offering prasādam.
(Krsna Book).

Another name of the Paramātmā feature of the Lord is kāla, or eternal time. Eternal time is the witness of all our actions, good and bad, and thus resultant reactions are destined by Him. It is no use saying that we do not know why and for what we are suffering. We may forget the misdeed for which we may suffer at this present moment, but we must remember that Paramātmā is our constant companion, and therefore He knows everything, past, present and future. And because the Paramātmā feature of Lord Kṛṣṇa destines all actions and reactions, He is the supreme controller also. Without His sanction not a blade of grass can move. The living beings are given as much freedom as they deserve, and misuse of that freedom is the cause of suffering. The devotees of the Lord do not misuse their freedom, and therefore they are the good sons of the Lord. Others, who misuse freedom, are put into miseries destined by the eternal kāla. The kāla offers the conditioned souls both happiness and miseries. It is all predestined by eternal time.
(Srimad Bhagavatam------1:8:28------purport).

Most of the gopīs in their previous lives were great sages, expert in the study of the Vedas, and when Lord Kṛṣṇa appeared as Lord Rāmacandra they wanted to enjoy with Him. Lord Rāmacandra gave them the benediction that their desires would be fulfilled when He would appear as Kṛṣṇa. Therefore the desire of the gopīs to enjoy the appearance of Lord Kṛṣṇa was long cherished. So they approached Goddess Kātyāyanī to have Kṛṣṇa as their husband. There are many other circumstances which also testify to the supreme authority of Kṛṣṇa and show that He is not bound by the rules and regulations of the material world. In special cases, He acts as He likes to favor His devotees. This is possible only for Him, because He is thesupreme controller. People in general should follow the instructions of Lord Kṛṣṇa as given in the Bhagavad-gītā and should not even imagine imitating Lord Kṛṣṇa in the rāsa dance.
(Krsna Book).

“The Supreme Personality of Godhead, Kṛṣṇa, therefore advised the cowherd men to stop the Indra-yajña and begin the Govardhana-pūjā to chastise Indra, who was very much puffed up at being the supreme controller of the heavenly planets. The honest and simple cowherd men, headed by Nanda Mahārāja, accepted Kṛṣṇa's proposal and executed in detail everything He advised. They performed Govardhana worship and circumambulation of the hill. According to the instruction of Lord Kṛṣṇa, Nanda Mahārāja and the cowherd men called in learned brāhmaṇas and began to worship Govardhana Hill by chanting Vedic hymns and offering prasādam. The inhabitants of Vṛndāvana assembled together, decorated their cows and gave them grass. Keeping the cows in front, they began to circumambulate Govardhana Hill.”
(Sri Caitanya Caritamrta-----2:4:86-------purport).

Lord Kṛṣṇa is the Supreme Controller and the Supreme Absolute Being, yet He never forces His will upon the infinitesimal living entities. Rather, it is to the living entity's own benefit to recognize that Lord Kṛṣṇa alone is the Supreme Personality of Godhead and that everyone else is His servitor. The sun-god and other demigods perform their duties according to Lord Kṛṣṇa's wishes; indeed, this is why they are called demigods. And since a devotee of the Supreme Lord also follows His wishes, he is also known as a sura, or demigod. Conversely, those who are oppose the Lord's wishes are known as asuras, demons.
(Renunciation through Wisdom).

By meditation one can understand that God is seated within one's heart. Even if one does not know it, God is seated within the heart of everyone. Not only is He seated in the heart of the human being, but He is also within the hearts of cats and dogs. Bhagavad-gītā certifies this fact by the declaration of the Lord, īśvaraḥ sarva-bhūtānāṁ hṛd-deśe (B.G.18:61). The īśvara, the supreme controller of the world, is seated in the heart of everyone. Not only is He in everyone's heart, but He is also present within the atom. No place is vacant or devoid of the presence of the Lord. That is the statement of Īśopaniṣad. God is present everywhere, and His right of proprietorship applies to everything. The feature of the Lord by which He is present everywhere is called Paramātmā. Ātmā means the individual soul, and Paramātmā means the individual Supersoul; both ātmā and Paramātmā are individual persons. The difference between ātmā and Paramātmā is that the ātmā, or the soul, is present only in a particular body, whereas the Paramātmā is present everywhere.
(Srimad Bhagavatam------3:15:45------purport).

There are different types of perfections known as siddhi-vraja, and also the perfections of achieving brahminical qualifications, yogic trance and merging into the Supreme. All these material perfections are certainly very attractive for a mundane person, but their brilliance exists only as long as one does not take to devotional service. Devotional service can control the Supreme Personality of Godhead, who is the supreme controller of all universal affairs. The five rasas (mellows) in the transcendental world are practiced by the inhabitants of Goloka Vṛndāvana in neutrality, servitorship, friendship, parental affection and conjugal love. All these please the Lord so much that He is controlled by the devotees. For instance, mother Yaśodā was so advanced in devotional service that Kṛṣṇa agreed to be controlled by her stick. In other words, the five principal mellows are so great and glorious that they are able to control the Supreme Personality of Godhead. In the material world, however, the so-called siddhis, or perfections, manifest their brightness only as long as one is not interested in devotional service. In other words, the perfection of the karmīs, jñānīs, yogīs and others remains attractive only as long as one does not come to the point of devotional service, which is so great and significant that it can control the supreme controller, Kṛṣṇa.
(Sri Caitanya Caritamrta-----2:19:165-------purport).

As such, what can they do for the satisfaction of the transcendental senses of Viṣṇu? And if they do not do everything for the satisfaction of the transcendental senses of Godhead, how can they expect to drag themselves or their followers from the mire of sins committed in the course of discharging prescribed duties? If the leaders do not recognize the existence of the all-powerful Viṣṇu, who is simultaneously both the supreme transcendental personality and the impersonal spirit existing everywhere, then what will ordinary men understand about Him? He is the supreme enjoyer of everything that be, and thus none of us, however great we may be, can be the enjoyer of the universe and its paraphernalia. Since our position is subordinate to that of the almighty Viṣṇu, the Supreme Godhead (Īśvara, the supreme controller), we can enjoy only what comes from Him as a token of His kindness. We must not enjoy anything that is not offered by Him. We should not make any extra effort to obtain anything which belongs to Him or others. That is the spirit of Vaiṣṇavism.
(Message of Godhead).

The Supreme Personality of Godhead is described as being without beginning. He is puruṣa, the Supreme Spirit. puruṣa means "person." When we think of a person in our present experience, that person has a beginning. This means that he has taken birth and that there is a history from the beginning of his life. But the Lord is particularly mentioned here as anādi, beginningless. If we examine all persons, we will find that everyone has a beginning, but when we approach a person who has no beginning, He is the Supreme Person. That is the definition given in the Brahma-saṁhitā. Īśvaraḥ paramaḥ kṛṣṇaḥ: (Bs. 5.1) the Supreme Personality of Godhead is Kṛṣṇa, the supreme controller; He is without beginning, and He is the beginning of everyone. This definition is found in all Vedic literatures.
(Srimad Bhagavatam------3:26:3------purport).

"Besides these innumerable fallible and infallible living beings there is another, superior personality, known as the Paramātmā. He pervades all the three worlds and exists as the supreme controller.
"And because I (Lord Śrī Kṛṣṇa) am transcendental to all of them, even those who are infallible, I am known in all the Vedas and histories (the Purāṇas, Mahābhārata, Rāmāyaṇa, etc.) as the Absolute Supreme Personality of Godhead."
(Light of the Bhagavata).

Śrīla Vyāsadeva at once accepts the supreme mind as the parameśvara, the supreme controller, and offers His respectful obeisances to Him. As stated in the Bhagavad-gītā and all other scriptures written by Śrīla Vyāsadeva, that parameśvara is Śrī Kṛṣṇa Himself. This is specifically stated in Śrīmad-Bhāgavatam. In the Bhagavad-gītā the Lord Himself says that there is no paratattva (summum bonum) other than Him. Therefore the author at once worships the paratattva, Śrī Kṛṣṇa, whose transcendental activities are described in the Tenth Canto.
(Teachings of Lord Caitanya).

The material disease is to declare independence from the supreme controller. Factually, our material existence begins when we forget the supreme controller and wish to lord it over material nature. Everyone in the material world is trying his best to become the supreme controller—individually, nationally, socially and in many other ways. Dhruva Mahārāja was advised to stop fighting by his grandfather, who was concerned that Dhruva was adhering to a personal ambition to fight to annihilate the whole race of Yakṣas. In this verse, therefore, Svāyambhuva Manu seeks to eradicate the last tinge of false ambition in Dhruva by explaining the position of the supreme controller. The words mṛtyum amṛtam, "death and immortality," are significant. In Bhagavad-gītā the Lord says, "I am ultimate death, who takes away everything from the demons." The demons' business is to continually struggle for existence as lords over material nature. The demons repeatedly meet death after death and create a network of involvement in the material world. The Lord is death for the demons, but for devotees He is amṛta, eternal life.
(Srimad Bhagavatam------4:11:27------purport).

So Śukadeva Gosvāmī has recommended to Parīkṣit Mahārāja that in order to be fearless of death, one has to hear and chant and remember the Supreme Personality of Godhead, Kṛṣṇa, by all means. He also mentions that the Supreme Personality of Godhead is sarvātmā. Sarvātmā means "the Supersoul of everyone." Kṛṣṇa is also mentioned as īśvara, the supreme controller who is situated in everyone's heart. Therefore, if some way or other we become attached to Kṛṣṇa, He will make us free from all danger. In Bhagavad-gītā it is said that anyone who becomes a devotee of the Lord is never vanquished. Others, however, are always vanquished. "Vanquished" means that after getting this human form of life, a person does not come out of the entanglement of birth and death and thus misses his golden opportunity. Such a person does not know where he is being thrown by the laws of nature.
(Nectar of Devotion).

"Kṛṣṇa, who is known as Govinda, is the supreme controller. He has an eternal, blissful, spiritual body. He is the origin of all. He has no other origin, for He is the prime cause of all causes." The Supreme Brahman (tad brahma) is the cause of all causes, but He has no cause. Anādir ādir govindaḥ sarva-kāraṇa-kāraṇam: (Bs. 5.1) Govinda, Kṛṣṇa, is the original cause of all causes, but He has no cause for His appearance as Govinda. Govinda expands in multifarious forms, but nevertheless they are one. As confirmed by Madhvācārya, ananyaḥ sadṛśābhāvād eko rūpādy-abhedataḥ: Kṛṣṇa has no cause nor any equal, and He is one because His various forms, as svāṁśa and vibhinnāṁśa, are nondifferent from Himself.
(Srimad Bhagavatam------6:4:30------purport).

A person who can control his senses fully is called vaśī, or self-controlled. In this connection it is stated in Śrīmad-Bhāgavatam, "All the sixteen thousand wives of Kṛṣṇa were so exquisitely beautiful that their smiling and shyness were able to captivate the minds of great demigods like Lord Śiva. But still they could not even agitate the mind of Kṛṣṇa, in spite of their attractive feminine behavior." Every one of the thousands of wives of Kṛṣṇa was thinking that Kṛṣṇa was captivated by her feminine beauty, but this was not the case. Kṛṣṇa is therefore the supreme controller of the senses, and this is admitted in Bhagavad-gītā, where He is addressed as Hṛṣīkeśa—the master of the senses.
(Nectar of Devotion).

The Supreme Personality of Godhead is undoubtedly equal to everyone. He has no friend and no enemy, but as one desires benefits from the Lord, the Lord is very pleased to award them. The lower and higher positions of different living entities are due to their desires, for the Lord, being equal to all, fulfills everyone's desires. The killing of Hiraṇyakaśipu and saving of Prahlāda Mahārāja also strictly followed this law of the supreme controller's activities. When Prahlāda's mother, Hiraṇyakaśipu's wife, Kayādhu, was under the protection of Nārada, she prayed for the protection of her son from the enemy, and Nārada Muni gave assurance that Prahlāda Mahārāja would always be saved from the enemy's hands. Thus when Hiraṇyakaśipu was going to kill Prahlāda Mahārāja, the Lord saved Prahlāda to fulfill His promise in Bhagavad-gītā (kaunteya pratijānīhi na me bhaktaḥ praṇaśyati (B.G.9:31) and to prove true the words of Nārada.
(Srimad Bhagavatam------7:9:29------purport).

From the platform of the material world, one cannot estimate the real position of the anti-material world. But the Supreme Lord, who is the controller of both material and anti-material energies, descends out of His causeless mercy and gives us complete information of the anti-material world. In this way we can know what the anti-material world is. The Supreme Lord and the living entities are both anti-material in quality, we are informed. Thus, we can have an idea of the Supreme Lord by an elaborate study of the living entities. Every living entity is an individual person. Therefore, the supreme living being must also be the supreme person. In the Vedic literatures the supreme person is properly claimed to be Kṛṣṇa. The name "Kṛṣṇa," indicating the Supreme Lord, is the only truly intelligible name of the highest order. He is the controller of both material and anti-material energies, and the very word "Kṛṣṇa" signifies that He is the supreme controller.
(Easy journey to other Planets).

"Kṛṣṇa, who is known as Govinda, is the supreme controller. He has an eternal, blissful, spiritual body. He is the origin of all. He has no other origin, for He is the prime cause of all causes." (Bs. 5.1)
Even in this material world, we can understand that the sun has existed for millions of years and has given off heat and light since its creation, yet the sun still retains its power and never changes. What then is to be said of the supreme cause, paraṁ brahma, Kṛṣṇa? Everything emanates from Him perpetually, yet He maintains His original form (sac-cid-ānanda-vigrahaḥ). Kṛṣṇa personally says in Bhagavad-gītā (10.8), mattaḥ sarvaṁ pravartate: "Everything emanates from Me." Everything emanates from Kṛṣṇa eternally, yet He is the same Kṛṣṇa and does not change. Therefore He is the shelter of all transcendentalists who are eager to get free from material bondage.
(Srimad Bhagavatam------8:3:15------purport).

Kṛṣṇa does not change His constitutional position, not even when He appears in this material world. Ordinary living entities have their constitutional spiritual positions covered. They appear in different bodies, and under the different bodily concepts of life they act. But Kṛṣṇa does not change His body. He appears in His own body and is therefore not affected by the modes of material nature. In the First Canto, Eleventh Chapter, verse 38, of Śrīmad-Bhāgavatam it is stated that the special prerogative of the supreme controller is that He is not at all affected by the modes of nature. The practical example of this is that devotees who are under the protection of the Lord are also not affected by material nature. To overcome the influence of material nature is very difficult, but the devotees or the saintly persons who are under the protection of the Lord are not affected. So what need is there to speak of the Lord Himself? To be more clear, although the Lord sometimes appears in this material world, He has nothing to do with the modes of material nature, and He acts with full independence in His transcendental position. This is the special quality of the Lord.
