Please be attentive to your own mind. See what a crowd is milling around therein, aimlessly, uselessly and without any effort on your part. Ask yourself, "To whom are these thoughts occurring? Who keeps looking at them? Who knows these are there?" Do not ask why they are occurring. They were occurring continuously. You were not attentive In fact, we dream more in the waking state than in the actual dream state. Become aware of this fact. It is important.
Like a machine, the mind works on incessantly. We ignorantly identify with this machine and start owing its working. That is the ignorance. Stand apart, which, in fact, you already are; simply become aware of this fact. Is it not the apple, already something other than the rest of the fruits? There are thoughts of sadness and anger, and you are something other than these thoughts, but you think you are the thoughts. 'I am sad, I am angry'. That is the tragedy! How could the 'seer' and the 'seen' be one?
