Gains:
don't treat your own with scorn,
don't go coveting those of others.
A monk who covets those of others
Attains no concentration.
Even if he gets next to nothing,
he doesn't treat his gains with scorn.
Living purely, untiring:
he's the one
that the devas praise.
-Dhammapada
It is necessary to cultivate some discipline of mind, for an undisciplined mind always finds excuses to act selfishly and thoughtlessly. When the mind is undisciplined, the body is also undisciplined, and so is speech and action.
-Anguttara Nikaya
Give your life for that cup of divine wisdom. How can you succeed without endurance and patience? To wait for the sake of that cup is no hardship. Show patience, for patience is the key to joy.
-Rumi
Poverty, the cruelest of demons, deprives a man
Of every joy in this life as well as the next.
-Tirukkural
He who does not long for joy in joy
Will not suffer sorrow in sorrow.
He who does not distinguish pain from pleasure
Becomes so distinguished even enemies hope to pay homage.
-Tirukkural
How far that little candle throws his beams! So shines a good deed in a naughty world.
-William Shakespeare
You will not be able to give anyone happiness by means of your wealth, so do it by means of a cheerful countenance and good humor.
-The Prophet Muhammad
