The Causal Ocean, He is lying there, sleeping within the ocean, and from His breathing the universes are coming out. This is God. Because He is in a sleeping condition, that is expansion of God. That is not original God. Original God is Kṛṣṇa. But he can expand Himself. Advaitam acyutam anādim ananta-rūpam ādyaṁ purāṇa-puruṣaṁ nava-yauvanaṁ ca (Bs. 5.33). That is God. Just have some idea what is God. So as Kāraṇodakaśāyī Viṣṇu, He is sleeping within the ocean, and as soon as there is question of sleeping, there is breathing also. The bubbles, the bubbles are expanding as universe. Yasyaika-niśvasita-kālam athāvalambya jīvanti loma-vilajā jagad-aṇḍa-nāthāḥ (Bs. 5.48). So breathing means exhaling, inhaling. So when the breathing, air is coming out, innumerable universes are coming into form, and when He is inhaling, then all of them becomes annihilated. This is material world. Material world means it comes into existence at a certain date, it remains for some time, it gives so many by-products, and it expands, and then dwindles, then finish. This is material, everything. Your body is like that, my body is like that. The whole universe is like that.
So here it is explained, mayā tatam idaṁ sarvam. This is God's impersonal expansion. When we cannot understand God, then we come first to the impersonal feature, everywhere, pantheism, which is known as, in philosophical terms, pantheism. There are different, I mean to say, ideas, and philosophical proposition. So this mayā tatam idam. But the pantheists, because the materialist think of limited... (coughs) They think that "God is everywhere. Therefore there is no personal God." No, that is foolish, foolishness. He is everywhere, it is explained here. Mayā tatam idaṁ sarvam: "By Me..." Mayā means, "by me." "By Me, or by My energy, I am expanded everywhere." Mayā, this word, it is causative. Causative means I have caused. The example is... If you want to understand, the example is very simple. Just like as soon as the sun is risen, immediately the sunshine is expanded.
