He that lives alone lives in danger; society avoids many dangers.

Nothing has such power to broaden the mind as the ability to investigate systematically and truly all that comes under thy observation in life.

He who does wrong does wrong against himself. He who acts unjustly acts unjustly to himself, because he makes himself bad.

Never value anything as profitable to thyself which shall compel thee to break thy promise, to lose thy self-respect, to hate any man, to suspect, to curse, to act the hypocrite, to desire anything which needs walls and curtains.

Give your heart to the trade you have learnt, and draw refreshment from it. Let the rest of your days be spent as one who has whole-heartedly committed his all to the gods and is thenceforth no man's master or slave.

A rational nature admits of nothing but what is serviceable to the rest of mankind.

Give full attention and devotion to each act.
