Judge not thy friend until thou standest in his place.
The more flesh, the more worms; the more possessions, the more worry.
If not you, who? If not now, when?
The shy man will not learn; the impatient man should not teach.
Golden Ruleโ: โThat which is hateful to you, do not do to your fellow. That is the whole Torah; the rest is the explanation; go and learn.
What you yourself hate, don't do to your neighbor. This is the whole law; the rest is commentary. Go and study.
