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.
Śyāmasundara: Like you defined miracle like that before once.
Prabhupāda: Yes. So there is nothing like miracle. Everything is done. But it is done so subtle way that we cannot understand. We take it chance. The same example: just like a child steps before the door; it opens. He thinks, "Oh, by chance the door is opened." But it is not by chance. It is a plan.
Śyāmasundara: By necessity.
Prabhupāda: Yes. No. Necessity you have to go and it is already done. And as soon as you step on the floor, the door opens. So those who are less intelligent, they are taking it as chance that "I came here. I wanted to go out. The door is by chance open." That is less intelligence.
Śyāmasundara: Oh. So before the necessity there is a plan. Previous to the necessity there is a plan. I see.
Prabhupāda: No, before the necessity, whoever we feel necessity, the chance is there. The arrangement is there. He knows that... Just like there may be hundreds and thousands of necessities, and for each necessity there is a planned performance.
