Śyāmasundara: If, for instance, in nature they saw a tree growing, they would say that by necessity this tree must die in order to replenish the soil so more trees can grow.
Prabhupāda: Then there is plan. As soon as you say that more trees can grow, that means there is plan. You cannot say chance.
Śyāmasundara: Nature can't be chance. If so many plants...
Prabhupāda: That plan is Kṛṣṇa's. That is said in the Bhagavad-gītā, mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram: (BG 9.10) "Under My plan, under My superintendence, the nature is working. The changes of the world is going on for that reason." Hetunānena kaunteya jagad viparivartate: "All these changes are taking place on account of My supervision." So there is no question of chance. It is all planned, planned by the Supreme, daiva netreṇa, by superior arrangement.
Śyāmasundara: Doesn't necessity mean plan?
Prabhupāda: Necessity means for a foolish person like me, I want something. That is my necessity and God supplies me. "Man proposes, God disposes." And that reception, or that, my achievement, being without explained by me, I take it as a chance. Because I cannot explain it, therefore I take... Just like the same example: the flower is fructifying. We are saying because we do not see how the working is going on.
