People idealize home and family, as if vaguely recalling some celestial correspondence. Yet most homes are rarely celestial, and often correspond to imprisonment and abuse that violates love. Over-emphasis on blood relations is often accompanied by a relatively loveless and unhappy bondage. So, instead of an oasis of culture, the usual home is only a karmic burning ground.
Ideally, a home would be a microcosm of true brotherhood. Brotherhood might begin in a good home, and would have far-ranging significance, because brotherhood transcends all the narrow groves of conventional clannishness.
