This gives a logical explanation of the law of cause and effect. A wrong-doer may escape earthly witnesses, 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 the good must return to him, as there is only one body and one life. Just as with the circulation in the physical body the essence of all we eat is absorbed in the blood, so our every thought, word and action affects the one life.
