Madhudviṣa: In the courtyard back at the temple I would like to grow one nim tree. Would that be nice?
Prabhupāda: Nim tree, how you can get?
Madhudviṣa: I think we can grow. Get some seed from India.
Prabhupāda: Yes. Scientists cannot purify the sea water and use it profusely. Why they are depending on rain? Let them purify it and take so much water.
Devotee: It's a very costly process, Śrīla Prabhupāda.
Prabhupāda: (laughs) Therefore I am asking.
Madhudviṣa: Kṛṣṇa is doing it. He is taking the water from the sea and putting it up in the sky, and it becomes very pure.
Prabhupāda: Millions and millions of tons water taken and distributed. Why their scientists so proud of their achievement? What they can do?
Madhudviṣa: Hm. It is amazing. There is no factory in the sky to purify the water. Simply by the evaporation of the sun, the water is held up in the sky, and immediately it comes down pure.
Prabhupāda: And it is stored on the mountain head and it comes down. Eternal supply. Whole year's supply through the rivers, huge water. You have seen that, what is name, Niagara Falls?
Madhudviṣa: Yes. You have seen? (laughter)
Prabhupāda: Yes. Huge water. There are many falls like that. Clean, clear, nice, sweet water is coming. There is sweet-water sea also.
Madhudviṣa: In the sea.
Prabhupāda: No, not here. In the sky. There is sweet water, very sweet, nice water, drinking water, sea. Sea of ghee, sea of yogurt, sea of milk. Everything is there.
