The second way to become the heart is to feel that inside you there is a divine Child and that is the soul. You can constantly think that inside your heart is a Child who is most luminous, infinitely more beautiful than any human being. The eternal Child needs an abode, a house, a room. Where is His room? It is inside your heart. First think of the Child, and then think of His needs. He needs a place to live and your heart is the most perfect abode.
The third way to feel that you are the heart is to constantly feel your need and God's need. Your need is perfection. If you can think of perfection, meditate on perfection, cry for perfection, then your need will be fulfilled. God's need is manifestation. In spite of your imperfection He is manifesting Himself, but when He can manifest in and through your perfection, then He will have real fulfilment. When God is fulfilling Himself in and through you, that is your real fulfilment and His real fulfilment. At that time you are nothing else but the heart.From:Sri Chinmoy,Mind-confusion and heart-illumination, part 2, Agni Press, 1974
