I am pleased by your wish to remain as brahmacari, and if you stick to your decision you will be able to go back to Godhead, back to Home, in this very life without waiting for another birth. Please try in every way to stick to this principle, and simply engage yourself in Krishna's service. That will protect you from any attack of maya. Maya can take Krishna's place in our heart as soon as there is a slackness on our part. Otherwise, if Krishna's seated always, maya has no opportunity to occupy the seat.
Letter to Upendra, 1 February, 1969
