This gives a logical explanation of the law of cause and effect. A wrongdoer may escape earthly witness, but he cannot escape this one life in which he lives and moves and has his being. A person who has done good to another may never see that other again, yet good must return to him because there is one body and one life. Just as with the circulation in the physical body all we eat is absorbed as essence in the blood, so our every thought, word and action affects the one life.
