Beware of too much laughter, for it deadens the mind and produces oblivion. — The Talmud. Central text of Rabbinic Judaism Laughter
Man has three friends on whose company he relies. First, wealth which goes with him only while good fortune lasts. Second, his relatives; they go only as far as the grave, leave him there. The third friend, his good deeds, go with him beyond the grave.
Whoever destroys a single life is as guilty as though he had destroyed the entire world; and whoever rescues a single life earns as much merit as though he had rescued the entire world.
Never expose yourself unnecessarily to danger; a miracle may not save you...and if it does, it will be deducted from your share of luck or merit.
He who carries out one good deed acquires one advocate in his own behalf, and he who commits one transgression acquires one accuser against himself. Repentance and good works are like a shield against calamity.
