Human nature is disposed to do good.

By exhaustively examining one's own mind,one may understand his nature.One who understands his own nature understands Heaven.

The way of truth is like a great highway. It is not hard to find.

He who exerts his mind to the utmost knows his nature.

The Way lies at hand yet it is sought afar off; the thing lies in the easy yet it is sought in the difficult.

The myriad things are complete in us. There is no greater joy than to reflect on ourselves and become sincere.

When Heaven is about to confer a great office upon you, it first exercises your mind with suffering and your sinews and bones with toil.
