When you are absorbed in love for God, His response is there at the heart center, a tremendous feeling of calmness and divine joy welling up in the heart that draws your attention or concentration to that center. That feeling in the heart is like a great comet of light; and in that light is the love of God. It is that feeling which you should concentrate on in the heart….As soon as I concentrate on the heart, I feel that light, that glow of God’s all-consuming love. - Paramahansa Yogananda.
