Question: Can you explain how the aspirant may reach his spiritual heart?

Sri Chinmoy: The spiritual heart is located right in the centre of the chest. Within the heart the soul abides. The soul permeates the whole body, but it abides in the heart, just as a man lives in a house, but stays most of the time in one certain room. One can feel the spiritual heart when one is aspiring intensely and one can also see it with the third eye. Every day each aspirant should concentrate on the heart and nowhere else. He has to feel that he does not have a head, he does not have legs, he does not have arms; he has only the heart. An aspirant can reach his spiritual heart through constant concentration and meditation.
