So the Supreme Personality of Godhead, līlāvatāra, incarnates in many forms, not only in the human society, but in the demigod society, or lower than human society, the animal society also, tree society. Because as we have forgotten our relationship with Kṛṣṇa, He's always anxious to get us back to home, back to Godhead, so He incarnates Himself in so many forms. Advaitam acyutam anādim ananta-rūpam (Bs. 5.33). He has got ananta-rūpa, unlimited forms. Advaitam acyutam anādi. But all those forms are in essence one. Advaita. That is not different.
Just like rāmādi-mūrtiṣu. The Lord appears as Lord Rāmacandra or as Lord Kṛṣṇa or as Lord Varāha. They are not different. In the material sense a varāha, a hog, is different from the man. Or the man is . . . one man is different from another man. But the incarnations of Kṛṣṇa, they are not different. The same thing.
Just like Kṛṣṇa, when He appeared, He, He's Kṛṣṇa when He was so-called three months old, and He was Kṛṣṇa when He was twenty years old. The same Kṛṣṇa. As we find difference that a . . . the same man, when he's three months old, he's different from the twenty years old. When his age is twenty years, he's different from his age when his age is three months.
The modern fashion is that they want to become God by meditation, by advancement of mystic power. But that kind of God is not Kṛṣṇa. Kṛṣṇa does not become God, He's God always. Others, they try to become God by mystic power. We have heard so many so-called Gods that, "He attained such perfection of mystic power. Now he has become God." That is also another māyā. Nobody can become God. God is God; dog is dog. This is the law of identity. A dog cannot become God, neither God becomes dog.
This is Māyāvāda theory, that at the end the Absolute Truth is void, or impersonal. The Buddhist theory is void and the Māyāvādī theory is impersonal. But our philosophy is that God is originally the Supreme Person. Brahmeti paramātmeti bhagavān iti śabdyate (SB 1.2.11). We have discussed this point many times.
Now, here it is said, līlāvatārānurato deva-tiryaṅ-narādiṣu. God is always anxious to get us back, back to home, back to Godhead. So apart from His incarnations amongst the deva, demigods . . . just like Upendra, Lord Vāmanadeva, He appeared amongst the demigods. There are so many other incarnation, demigods. Tiryaṅ . . . Narādi . . . Tiryaṅ. God appeared as incarnation of boar, incarnation of horse, incarnation of tortoise.
