Lecture on SB 1.7.30-31 -- Vrndavana, September 26, 1976:

This is the process, going on. Bhūtvā bhūtvā pralīyate (BG 8.19). This material world, in this way, sometimes it is manifested and sometimes it is not manifested. The energy is there, but the material world means the energy sometimes manifested, sometimes not manifested. So we are in this material world. Not only. We are changing our body, one after another after some years... That is also according to our different forms of life. In one small insect, it may live for few minutes; some of them for few hours, some of them for few days, and some of them for few months, some of them for few years. And this yearly, we live, we human being, we live for a hundred years, and the demigods, they live for ten thousands of years. But wherever you live, either as insect or as demigod, there is no rescue from the process of janma-mṛtyu-jarā-vyādhi (BG 13.9). That you cannot escape.

We have calculation in the Bhagavad-gītā, that sahasra-yuga-paryantam ahar yad brahmaṇo viduḥ (BG 8.17). Sahasra-yuga. One yuga means forty-three lakhs of years multiplied by one thousand. That is the one daytime duration of Brahmā. Ahar rātri means morning to evening. Morning to evening, that is sahasra-yuga, one thousand times of forty-three lakhs of years. Similarly night. Then day and night becomes one day. Similarly one month, and then twelve months, a year—such hundred years. So there is difference between our hundred years and his hundred years. Similarly, ant's hundred years and my hundred years different.
