BOOKS ARE THE BASIS
"There is no literature throughout the universe like Srimad Bhagavatam. There is no comparison. There is no Competition. Every word is for the good of human society. Somehow or other, if a book goes in someone's hand, he will be benefited… Therefore we are stressing so much, 'Please distribute books, distribute books, distribute books'" – Srila Prabhupada.
