Bhagavad-gita As It Is Lectures

Lecture on BG 8.15-20 -- New York, November 17, 1966:

Sahasra-yuga means... One yuga means forty-three lakhs of years. Then that means 4,300,000's of years. That is the duration of one yuga. And sahasra-yuga... And sahasra means thousand. That 4,300,000 of years, just multiply it by another one thousand. Now we calculate. I am not mathematician. You can calculate what is that duration. So that duration, long duration, forty-three, five zero, into one thousand, that means forty-three, five zero, again three zero. Now, what is that duration? That is calculated to be twelve hours of Brahmā. As you have got twelve hours from morning, six, to evening, six. So this duration of period in the Brahmaloka is forty-three and five zero into three zero. Just imagine. That is twelve hours. Similarly, another twelve hours-night, same period. So that becomes one complete twenty-four hours of Brahmā. Brahmaloka. And such one month, and such one year, and one hundred years duration of life is there. Sahasra-yuga-paryantam ahar yad brahmaṇo viduḥ (BG 8.17). That is the duration of life there. You cannot calculate how long you can live there. But still, after so many years, millions and trillions of years' life, you'll have to die. Death is there. Death, you cannot... Unless you go into the spiritual planets, there is no escape from death. So ābrahma-bhuvanāl lokāḥ, ābrahma..., yuga-paryantam,

sahasra-yuga-paryantam

ahar yad brahmaṇo viduḥ

rātriṁ yuga-sahasrāntāṁ

te 'ho-rātra-vido janāḥ

(BG 8.17)

Avyaktād vyaktayaḥ sarvāḥ prabhavanty ahar-āgame. Now, this duration of Brahmā, the, the material manifestation in the lower status, this planetary system, when Brahmā days is finished, all these planetary systems becomes covered in water. There is devastation, devastation, and when again Brahmā, the supreme person in the Brahmaloka, he rises up, then again creation begins. That is the law of creation. So avyaktād vyaktayaḥ sarvāḥ prabhavanty ahar-āgame. Ahaḥ. Ahaḥ means in the daytime. When there is daytime, daytime, twelve hours, then this material manifestation, what you see, all these planets, they are manifested, seen. But when there is nighttime, all these planetary system becomes merged into devastation of water. So rātry-āgame pralīyante tatraiva avyakta-saṁjñake. Rātry-āgame means when the night is there, then again all these planets become invisible. They are devastated within the water. This is the nature of this material world. Bhūta-grāmaḥ sa evāyaṁ bhūtvā bhūtvā pralīyate (BG 8.19). So because the whole planetary system becomes, I mean to say, merged into devastation of water, therefore all living entities, they, at that time, pralaya, devastation, they all die. Bhūta-grāmaḥ sa evāyaṁ bhūtvā bhūtvā pralīyate (BG 8.19).
