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.
