Bread Quotes - page 29
Those who observe the nature of the Universe and the commandments of the Law, and know their purpose, see clearly God's mercy and truth in everything; they seek, therefore, that which the Creator intended to be the aim of man, viz., comprehension. Forced also by claims of the body, they seek that which is necessary for the preservation of the body, "bread to eat and garment to clothe," and this is very little; but they seek nothing superfluous; with very slight exertion man can obtain it, so long as he is contented with that which is indispensable.
Maimonides
