"We reduce, concretize, or substantialize experiences or feelings, which are, in their very nature, fleeting or evanescent. In so doing, we define ourselves by our moods and by our thoughts. We do not just let ourselves be happy or sad, for instance; we must become a happy person or a sad one. This is the chronic tendency of the ignorant or deluded mind, to make "things" out of that which is no thing."
