Now coming to spiritual attainment: this is something that we can never absorb through the head; it can only be received through the heart. Let two persons listen to the teachings of a teacher, one with his heart and the other with his head. The latter will think, "Is it so, or is it not so? And how is it, if it is so? How can it be, and if it is, why is it?" And there is never an end to the "why." The other person will listen with his heart; both logic and reason are at his disposal, but they do not trouble him. His heart is open, he listens to it and the quality of the heart is such that whatever falls upon an open heart becomes instantly revealed. When one says, "I cannot understand you" it is just like saying, "I have closed my heart to you"; there is no other reason for not understanding. And when one says, "I have understood it all," it means the heart was open; that is why one has understood.
