Vyāsadeva was, when he was instructed by his spiritual master Nārada Muni to write Śrīmad-Bhāgavatam, at that time, by bhakti-yoga meditation, he could see the Supreme Personality of Godhead and this māyā also. But it is said, māyāṁ ca tad-apāśrayam. Māyā is situated in the back side, back side, without any influence upon Kṛṣṇa, apāśrayam, under the control. So māyā is always controlled. Kṛṣṇa is the controller of māyā.
In another place, in the Brahma-saṁhitā, it is said, sṛṣṭi-sthiti-pralaya-sādhana-śaktir ekā chāyeva yasya bhuvanāni bibharti durgā (Bs. 5.44). Durgā is the material energy, and she has got immense power. Sṛṣṭi-sthiti-pralaya-sādhana-śaktiḥ. She is controlling this creation, or this whole universe, sṛṣṭi, and sthiti, its maintenance, and pralaya. Three things she is controlling. She is so powerful. Sṛṣṭi-sthiti-pralaya-sādhana-śaktir ekā chāyeva yasya bhuvanāni bibharti durgā. The durgā-śakti, material energy, she is so powerful, but it is working chāyeva, just like shadow. Shadow has no independent capacity; it is dependent on the substance. Substance and shadow. So Kṛṣṇa is the substance, and the power derived from Kṛṣṇa, partially exhibited by the durgā-śakti. In the Upaniṣad also it is said, na tasya kāryaṁ karaṇaṁ ca vidyate na tat-samaś cābhyadhikaś ca dṛśyate (Śvetāśvatara Upaniṣad 6.8). Kṛṣṇa, the Supreme Personality of God, He has nothing to do. Na tasya kāryaṁ karaṇaṁ ca vidyate na tat-samaḥ. Nobody is equal to Him. Kṛṣṇa also says in the Bhagavad-gītā, mattaḥ parataraṁ nānyat kascit (BG 7.7): "There is nothing superior than Me, the Supreme." In the Śrīmad-Bhāgavatam also it is said, oṁ namo bhagavate vāsudevāya, satyaṁ paraṁ dhīmahi (SB 1.1.1). That is the Supreme Truth.
So all the śāstras will say that Kṛṣṇa, or the Supreme Personality of Godhead, He has got different expansions unlimited. Although Kṛṣṇa is one, but He can expand Himself into many, many millions. Advaitam acyutam anādim ananta-rūpam (Bs. 5.33). Ananta-rūpam. And each rūpam is acting in some universe. Just like at this time, here, you find darkness in Bombay, but the sun is present in all his different phases all over the world. Sun rises in the morning at, say, seven o'clock. So this seven o'clock to next seven o'clock, in the evening seven o'clock, you will find, if you immediately take information, somewhere it is seven o'clock, somewhere it is twelve o'clock, somewhere it is six o'clock, somewhere it is . . . all the time formula of the sun is present, although we are seeing there is no sun. Similarly, Kṛṣṇa is present throughout the whole universe in some feature. In one universe you will find Kṛṣṇa is taking birth, janmāṣṭamī. In some universe you will see Kṛṣṇa is playing with the cowherd boys. Somewhere it is . . . in this way. Therefore it is called nitya-līlā. Nitya-līlā means the janmāṣṭamī-līlā is going on permanently somewhere or other. Therefore it is called līlayā, yadṛcchayā.
So this is a great science, Kṛṣṇa science, kṛṣṇa-tattva. So we have to learn from the authorized Vedic literature about Kṛṣṇa. And that is required in human life. Because if we simply understand the truth about Kṛṣṇa, janma karma ca me divyam (BG 4.9), which are divine, transcendental, yo jānāti tattvataḥ, if you try to understand and if you become fortunate to understand the divine nature of Kṛṣṇa's līlā, then you become liberated, immediately: tyaktvā dehaṁ punar janma naiti mām eti kaunteya (BG 4.9). The Sāṅkhya philosophy of Kapiladeva is explained in this way to understand Kṛṣṇa.
So Kṛṣṇa, yadṛcchayaivopagatām abhyapadyata līlayā. Kṛṣṇa is līlā, and our coming here is not līlā. We are forced. We are forced. Karmaṇā daiva-netreṇa dehopapattaye (SB 3.31.1). Kṛṣṇa's body is sac-cid-ānanda-vigraha (Bs. 5.1). Kṛṣṇa's body is not material. Even if we think it is material, still, it is sac-cid-ānanda-vigraha. Just like one can argue that, "Here is Kṛṣṇa's form. It is made of stone. How it is sac-cid-ānanda-vigraha?" But if you know the nature of Kṛṣṇa, even He appears as stone, still He is sac-cid-ānanda-vigraha. How? Because the stone is also energy of Kṛṣṇa.
