1 Kings 19:4

There is no guilt greater than to sanction ambition; no calamity greater than to be discontented with one's lot; no fault greater than the wish to be getting. Therefore the sufficiency of contentment is an enduring and unchanging sufficiency.

It hath been said that Self-restraint is an excellent vow for all the four modes of life. I regard those attributes as its indications which owe their origin to self-restraint. Those indications are forgiveness, firmness of mind, abstention from injury, an equal regard for all things, truthfulness of speech, simplicity, control over the senses, patience, gentleness of speech, modesty, steadiness, liberality, mildness, contentment, and faith, he that hath self-restraint casteth off lust, avarice, pride, wrath, sleep, boastfulness, self-esteem, malice, and sorrow. Purity and absence of crookedness and fraud, are the distinctive marks of a man of self-restraint. He that is not covetous, that is satisfied with a little, that regardeth not objects provoking lust, and that is as grave as the ocean, is known as a man of self-restraint. He that is well-behaved, of good disposition and contented soul, that knoweth his own self is possessed of wisdom, winneth great regard here and attaineth to a blissful state hereafter. Possessed of mature wisdom, he that hath no fear of other creatures and whom other creatures fear not, is said to be the foremost of men. Seeking the good of all, he is a universal friend, and no one is made unhappy by him. Endued with gravity, like that of the ocean and enjoying contentment in consequence of his wisdom, such a man is always calm and cheerful. Regulating their conduct according to the acts practised by the righteous olden times and before their eyes, they that are self-restrained, being devoted to peace, rejoice in this world. Or, abandoning Action, because contented in consequence of Knowledge, such a person, with his senses under control moveth quickly in this world, waiting for the inevitable hour and absorption into Brahma. And as the track of feathery creatures in the sky is incapable of being perceived, so the path of the sage enjoying contentment in consequence of Knowledge is not visible.

(How) that wherewith they were contented naught availeth them?

Then, when they had finished their work and the meal was ready, they ate it, and every man had his full share so that all were satisfied. As soon as they had had enough to eat and drink, they laid down to rest and enjoyed the boon of sleep.
