The more you talk and think about it, 

The further astray you wander from the truth. 

Stop talking and thinking, 

And there is nothing you will not be able to know.

Jianzhi Sengcan (?-606 CE), Jianzhi Sengcan is known as the Third Chinese Patriarch of Chán after Bodhidharma and thirtieth Patriarch after Siddhārtha Gautama Buddha.
