I am in due receipt of your letter dated March 27, 1976 with enclosed cassette tape and I thank you very much. I very much liked the chanting on this tape. It is very excellent and should be popularized and it will be a great success. Introduce this into every home and that will help them, and if they read our books then finished, no more material life.
Letter to Krishna Kanti das, 6 April, 1976
