When Yang-shan Hui-chi (807-883), as a young monk, paid a visit to the Ch'an master Hsing-k'ung, there was a monk who asked Hsing-k'ung:
-What is the meaning of the Patriarch's coming from the West?
And what is the Ego. The Ego is the one that is full of thoughts.

No thought has power by itself. All thoughts are equal in weightlessness. A thought cannot think itself. No thoughts is self employed. A thought cannot survice without contact with you with your beliefs. The mind is not sentient. Sentient means it is not source of the existence. Mind does not have will. Mind has no light by its own. Mind has no power. Mind only has the power of belief.
