"Everywhere, either you are at home or you are outside, either you are young, you are old, either you are scientist or philosopher. Whatever you are, the material nature will not allow you to live in peaceful condition. That is her business. Daivi hy esa gunamayi mama maya duratyaya [Bg. 7.14]. You cannot live peacefully, that is not possible. The only peaceful condition is that you become in Krishna consciousness. There is no other alternative. Kalau nasty eva nasty eva nasty eva gatir anyatha. Lord Caitanya clearly says, 'There is no other alternative, no other alternative, no other alternative.'"
(Srila Prabhupada lecture, Los Angeles, December 6, 1968)
