Śrīmad-Bhāgavatam 1.8.28 - Māyāpura, October 8, 1974
So Kṛṣṇa, manye tvāṁ kālam īśānam. Eternal time. We are calculating past, present and future, but actually in the spiritual world, there is no such thing as past, present and future. We therefore sometimes question that "Wherefrom God came?" So many odd questions they say. But God is eternally existing. That is the fact. We cannot understand that. Because we are in the material world, we have no experience of the eternity, what is eternity. We have no experience. We see everything as generated, and then it stays for some time, then it is finished. That is our experience. Janma, mṛtyu, vṛddhi.
They have... They have made past, present and future, but it is divided into six development. One takes birth, then it develops, then it stays for some time, then it produces some by-product, then diminishes, and then, I mean to say, finished. Ṣaḍ-vikāra. Ṣaḍ-vikāra. This body, ṣaḍ-vikāra. So eternity, eternity means there is no ṣaḍ-vikāra, the six kinds of changes. There is no birth. There is no death. There is no diminishing. There is no by-product. Everything eternal, eternally existing.
