The yuga year means forty-three hundred thousands of years, and multiplied by one thousand, that period is Brahmā's twelve hours, day. Now you can imagine . . . It is beyond your mathematical calculation, but still, there is calculation in the śāstra, and that is, such hundred years is the duration of sthiti. But that sthiti, before Kāraṇodakaśāyī Viṣṇu, is the moment, just like we exhale and inhale. So sṛṣṭi-sthiti. Yasyaika-niśvasita-kālam athāvalambya (BS 5.48). They take only that much time which is between exhaling and inhaling. That Mahā-Viṣṇu. That Mahā-Viṣṇu has placed Himself in this material energy, maha-tattva, and by His niśvasa, by His inhaling and exhaling, the material energy is agitated. Then the three guṇas are there. Then, by interaction, counteraction, the whole creation takes place.
Nyasyedam ātmani jagad vilayāmbu-madhye śeṣe. Śeṣe: "Lying down on the Śeṣa-mūrti." Ātmanā nija-sukhānubhavo . . . "He is not obliged, as we are placed in certain condition of life, being obliged." Karmaṇā daiva-netreṇa (SB 3.31.1). I have got this body; you have got this body. It is not sukhānubhavaḥ. Here it is said that nija-sukhānubhavaḥ. This is called pastime. He is not obliged, but he takes pleasure. Just like sometimes we take pleasure in the swimming pool, lie down and closing our eyes. Who are expert swimmer, they're lying down. Why it is not possible for the Supreme Lord? (laughter) What is the difficulty? Sukhānubhavaḥ. We take that pastime for pleasure, for pleasure, lying down on the water, closing eyes. So when we speak, "The Garbhodakaśāyī Viṣṇu lying down in the Causal Ocean," these rascals, fools, they sometimes criticize, "And how it is possible?"
