Please therefore chant very sincerely with your present aptitude of mind and Krishna will bless you more and more in understanding this secret of transcendental vibration. Of course, sometimes the public may misunderstand such tears of bliss, so we may better have to check it from the vision of ordinary persons. So far the strange colors, etc., better when you see all these things that you chant and hear; that will help you to understand what they are.
Letter to Jayapataka, 11 March, 1969
