Nānā-śāstra-vicāraṇaika-nipuṇau: they were expert in scrutinizingly studying all the scriptures. Nānā-śāstra-vicāraṇaika-nipuṇau. Nipuṇau means expert. Why? Sad-dharma-saṁsthāpakau: to establish real religion in the world. Real religion. Just yesterday we have received one letter from Mr. Renovich, Vancouver. He says that the Canadians, they want real religion. That is very good, encouraging. Anyone, if he is anxious to have real religion, for him this is the best thing, this kṛṣṇa-kīrtana-gāna-nartana. So without religion, human society is nothing but animal society. It is simply polished animalism.
So these Gosvāmīs, they made so many books to guide us. You have read Rūpa Gosvāmī's Bhakti-rasāmṛta-sindhu. That is the first direction in the line. So they always worked very hard, day and night. Their business was writing books or chanting and dancing. And other necessities—eating, sleeping, mating and fearing—they practically abolished. There was no question of mating; there was no question of fearing. And sleeping, they used to sleep utmost one and a half hour daily in twenty-four hours. And eating, that is also practically nil. When they felt hungry they would go to some householder's home and beg one cāpāṭi or two cāpāṭis. That's all. Finished.
So nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma-saṁsthāpakau. Why? Lokānāṁ hita-kāriṇau. The mission of saintly person is simply to think how this suffering humanity will become happy by spiritual consciousness. That is their business. They are not for exploiting. The whole material world is trying . . . one man is trying to exploit another; one nation is trying to exploit another nation; one society is trying to . . . this is struggle for existence. They have invented this law that, "Might is right." You struggle, and if you are powerful . . . just like there is now a struggle between Russia and America, or China and America. This is going on.
