Please accept my thanks and blessings of Lord Krishna for your letter of the 12th instant describing your meeting with a Maya the illusory energy and combating her by Krishna consciousness. In future if any one challenges our philosophy one may put his questions in writing and must be prepared to receive the answers from human understanding. We cannot talk with any one who is not within the purview of human understanding. You are completely right when you refuse to debate and accept invitation for chanting Hare Krishna Mahamantra. Although we should not chant in a society which is disruptive but as soon as one invites us for chanting we take it for granted that they are friendly and we must take the opportunity.
