A wise man should not divulge the formula of a medicine which he has well prepared; an act of charity which he has performed; domestic conflicts; private affairs with his wife; poorly prepared food he may have been offered; or slang he may have heard.

The wise man makes an island of himself that no flood can overwhelm.

The highest wisdom has but one science - the science of the whole - the science explaining the whole creation and man's place in it.

The foolish man conceives the idea of 'self.' The wise man sees there is no ground on which to build the idea of 'self;' thus, he has a right conception of the world and well concludes that all compounds amassed by sorrow will be dissolved again, but the truth will remain.

You can't be wise and in love at the same time.

Knowledge is merely brilliance in organization of ideas and not wisdom. The truly wise person goes beyond knowledge.
