There is no question of believe. Don't bring this question-belief. It is law. Just like there is government, you believe or not believe, who cares for you? That is government. Similarly, you believe or not believe, there is God. If you don't believe in God and do independently whatever you like, then you'll be punishable.
-Radio Interview -- July 27, 1976, London

नैनं छिन्दन्ति शस्त्राणि नैनं दहति पावकः ।
न चैनं क्ल‍ेदयन्त्यापो न शोषयति मारुतः ॥ २३ ॥
The soul can never be cut to pieces by any weapon, nor burned by fire, nor moistened by water, nor withered by the wind.
-BG 2.23
