The sovereign good of man is a mind that subjects all things to itself and is itself subject to nothing; such a man's pleasures are modest and reserved, and it may be a question whether he goes to heaven, or heaven comes to him; for a good man is influenced by God Himself, and has a kind of divinity within him.
Seneca the YoungerIt is man's duty to live in conformity with the divine will, and this means, firstly, bringing his life into line with 'nature's laws', and secondly, resigning himself completely and uncomplainingly to whatever fate may send him. Only by living thus, and not setting too high a value on things which can at any moment be taken away from him, can he discover that true, unshakeable peace and contentment to which ambition, luxury and above all avarice are among the greatest obstacles.
Seneca the Younger
