It would be wrong to withhold aid from someone suffering by saying: “You yourself are the cause of the trouble,” refuse him help because it must work itself out. That is a misunderstanding of Karma. Karma, to the contrary, says to you: “Help him, who suffers, for you exist to help”. You help to improve the credit balance of the Karmic account of necessity when aiding your fellow man. You give him the opportunity and the strength to carry his Karma; and you, to that extent, are a redeemer from evil.
