Whenever I ger report of my books selling, I feel strength. Regarding book sales figures, please endeavor in this way. This is the only solace of my life. When I hear that my books are selling so nicely, I become energetic like a young man. – Srila Prabhupada, Sep 1974.
Knowledge of Scriptures is Transcendental. Knowledge of Books of this World is Material.
Simply we have to desire to please Him (Krishna) and not desire anything for ourselves. Then we become simply instrument for his will. This is the important essence of Krishna consciousness. — In his Letter to Atreya Rishi, 20th Oct, 1973.
We have no freedom not to serve Krishna; we have choice.
