100. Question: How can I hear the soundless sound?Sri Chinmoy: You can hear the soundless sound provided you concentrate on your heart centre and try to feel that your spiritual heart is much larger than the universe itself. Try to feel that the heart is the house, the universe is a room and the soundless sound is an object in the room. If you can soulfully concentrate on the spiritual heart and imagine the things that I am asking you to, then you will hear the soundless sound.
