Even by looking at Prabhupada's picture, you feel that beautiful spiritual potency. I was lucky enough to find an old edition of the Bhagavad-Gita: As It Is in a used bookshop almost 10 years ago. It was printed before things were changed, and it's very precious to me. Prabhupada's gift to the world was bringing the Maha Mantra to everyone, and that can't be corrupted.
