There is no greater truth than this – you only know you are truly helping people when you are getting criticized – the reason is simple, as the Baal Shem Tov would cry – for he saw how good people would get attacked by bad people and he explained: a person carrying a bundle of grass, gets attacked by no-one, but s/he who carries gemstones, diamonds and rubies, many a bad person will try to rob them – can there be a great treasure than a loving heart?
