Death hangs over thee, While thou still live, while thou may, do good.
The one thing worth living for is to keep one's soul pure.
Whosoever does wrong, wrongs himself; whosoever does injustice, does it to himself, making himself evil.
Let no act be done without purpose.
Life is neither good or evil, but only a place for good and evil.
Keep constantly in mind in how many things you yourself have witnessed changes already. The universe is change, life is understanding.
