““Idle thoughts come and go over unenlightened minds six hundred and fifty times in a snap of one's fingers," writes an Indian teacher,[FN#260] "and thirteen hundred million times every twenty-four hours." This might be an exaggeration, yet we cannot but acknowledge that one idle thought after another ceaselessly bubbles up in the stream of consciousness. "Dhyana is the letting go," continues the writer—"that is to say, the letting go of the thirteen hundred million of idle thoughts." The very root of these thirteen hundred million idle thoughts is an illusion about one's self. He is indeed the poorest creature, even if he be in heaven, who thinks himself poor. On the contrary, he is an angel who thinks himself hopeful and happy, even though he be in hell.””
