He who seeking his own happiness does not punish or kill beings who also long for happiness, will find happiness after death. Buddha
Rouse thyself! do not be idle! Follow the law of virtue! The virtuous rests in bliss in this world and in the next. Buddha
He who can withstand in this world, before the liberation from the body, the impulse arising from lust and anger, he is steadfast, he is a happy man. Lord Krishna
The uncharitable do not go to the world of the gods; fools only do not praise liberality; a wise man rejoices in liberality, and through it becomes blessed in the other world. Buddha
Victory breeds hatred, for the conquered is unhappy. He who has given up both victory and defeat, he, the contented, is happy. Buddha
He by whom the world is not agitated and who cannot be agitated by the world, who is freed from joy, envy, fear, and anxiety—he is dear to Me. Lord Krishna
The sight of the elect is good, to live with them is always happiness; if a man does not see fools, he will be truly happy. Buddha
