If we live in our oneness-heart, we will feel the essence of all religions, which is love of God. But if we live in the mind, we will only try to separate one religion from another and see how their ideologies differ. It is the heart that can have a true intuitive understanding of the height and breadth of all religions. It is the heart that sees and feels the inner harmony and oneness of all religions.
Sri ChinmoyHow can one know who his spiritual teacher is?...His heart looks at the spiritual Masters and makes the choice. When the heart sees a spiritual Master, if it is overwhelmed with joy, then there is every probability that that spiritual Master is the right one for the seeker.
