We in our humble way are trying to spread this cult of Bhagavad-gita all over the world, and my American and European disciples, two samples of them are meeting with you, are helping me in this connection. After all, Bhagavad-gita is the sublime cultural knowledge, and of course religion is included there, but it is not fanaticism or sentimental religion. It is based on pure science, philosophy, and logic.
Letter to Srimati Indira Gandhi, Prime Minister of India, 6 November, 1973
