So far going to the moon planet is concerned, don't be very much interested in moon travel. Better that you travel on this planet and serve Krishna. We don't care for such moon travel. Rather after this life we want to travel to Krishna. If even we go to Brahmaloka, the topmost planet, still we have to come down. So let the foolish waste their time in this way, while we will go directly to Krishna.
Letter to Vaikunthanatha, 6 September, 1971
