But there is restriction. How there is restriction? When people become godless, there is restriction of supply. Just like practical experience. I am saying from my practical experience that in my childhood I saw that India was exporting millions of tons of rice and wheat and other grains also, oil seed grains, huge export business. That India is now begging grains from other countries. You see. Why? Because they are gradually becoming godless. The population theory I don't believe, because if Kṛṣṇa is supplying, eko bahūnāṁ vidadhāti kāmān... And actually we find that there is no population problem. Amongst the animals, amongst the birds, there is no contraceptive method. They are increasing their population, and they are being fed by God. So why in the human society the population theory is so acute? Because they are becoming less than animals. The animals, they beget, they mate at a certain period, but a human being, at the present moment, they have no such restriction. Any time. Therefore they want contraceptive method.
So this godless civilization is so acute that it is very difficult to make them understand God consciousness or Kṛṣṇa consciousness. But still, as a matter of duty, we have to present, submit, these teachings of Bhagavad-gītā and Śrīmad-Bhāgavatam because we are following the teachings of Lord Caitanya, who wanted. He said that pṛthivīte āche yata nagarādi grāma. All over the world in all the cities and all the villages, everywhere this philosophy of harer nāma harer nāma harer nāma eva kevalam, kalau nāsty eva nāsty eva nāsty eva gatir anyathā (CC Adi 17.21), this philosophy should be preached.
