When a monk came to say good bye to Chao-chou Tsung-shen (778-897), a brilliant Chinese Ch'an master.
-Where will you go?
The monk answered:
-Any place where I can learn Buddha dharma.
Sometimes I am confused whether I am thinking thoughts, or whether thoughts enter from elsewhere. Because it is impossible to think a thought and recognize you are the thinker while you are thinking the thought.
Try to be aware of a your mind and at the same time try to recite something in your head. It doesn't work. At best it is an on-off switch (thought-thinker-thought-thinker...)
