A Composition Urging The Generation Of The Bodhi Mind
By Ch'an Master Shih-Hsien Hsing-An

Translated by Dharma Master Lok To
Edited by Dr. Frank G. French

If, even though you have heard thatit takes a very long time to attain the Buddha stage,you  do not fear and never think of regressing or giving up,and if, even though it appears to be almost impossibly difficultto convert all sentient beings,you never tire, but, on the contrary,as if climbing the highest mountainyou must, of necessity,want to arrive at the peak or,as if ascending a tall toweryou urgently want to reach the top,continuing tirelessly and with good faith --just this kind of thought is called True Thought.
