Buddha has said to his disciples: Whenever you meditate, after each meditation, surrender all that you have earned out of meditation, surrender it to the universe. If you are blissful, pour it back into the universe - don't carry it as a treasure. If you are feeling very happy, share it immediately - don't become attached to it, otherwise your meditation itself will become a new process of the self. And the ultimate meditation is not a process of self. The ultimate meditation is a process of getting more and more into un-self, into non-self - it is a disappearance of the self.
