Always first draw fresh breath after outbursts of vanity and complacency.

Association with human beings lures one into self-observation

There is nothing with which every man is so afraid as getting to know how enormously much he is capable of doing and becoming

A man who as a physical being is always turned toward the outside, thinking that his happiness lies outside him, finally turns inward and discovers that the source is within him
