Do not unto others that which is hateful unto thee.
The more flesh, the more worms; the more possessions, the more worry.
If not you, who? If not now, when?
If I am not for myself, then who will be for me? But when I am for myself, then what am "I"? And if not now, when?
Be of the disciples of Aaron, loving peace and pursuing peace, loving your fellow creatures and drawing them near to the Law.
Judge not thy friend until thou standest in his place.
