"Ramana Maharshi: There is happiness when agreeable things are presented to the mind. It is the happiness inherent to the Self, and there is no other happiness. And it is not alien and afar. You are diving into the Self on those occasions which you consider pleasurable; that diving results in self-existent bliss. But the association of ideas is responsible for foisting that bliss on other things or occurrences while, in fact, that bliss is within you. On these occasions you are plunging into the Self, though unconsciously. If you do so consciously, with the conviction that comes of the experience that you are identical with the happiness which is verily the Self, the one Reality, you call it Realization. I want you to dive consciously into the Self, i.e., into the heart."
