"Prior to the cosmic creation, only I exist, and no phenomena exist, either gross, subtle or primordial. After creation, only I exist in everything, and after annihilation, only I remain eternally.
Aham means "I"; therefore the speaker who is saying aham, "I," must have His own personality. The Māyāvādī philosophers interpret this word aham as referring to the impersonal Brahman. These Māyāvādīs are very proud of their grammatical knowledge, but any person who has actual knowledge of grammar can understand that aham means "I" and that "I" refers to a personality. Therefore the Personality of Godhead, speaking to Brahmā, uses aham while describing His own transcendental form. Aham has a specific meaning; it is not a vague term that can be whimsically interpreted. Aham, when spoken by Kṛṣṇa, refers to the Supreme Personality of Godhead and nothing else.
