Karma may have brought it about that in youth we grew angry, and condemned this or that human action. If we retain this quality we have made poor use of our lives. We have used them well, supposing we formed harsh judgments in our youth, if at a later stage of life we do not judge harshly, but with understanding and forgiveness; if we make the effort of wishing to understand.
If we have the character that from birth some things aroused furious anger in us, and if when we are old we no longer grow angry as in our youth, but our anger has left us and we have grown gentler — then we have used life in accordance with wisdom. If we were materialists in our youth, but then allowed ourselves to experience what our time could bring us as revelations from the spiritual world, then we have used our life in accordance with wisdom. If we close ourselves to the revelations of the spiritual world we have not used our life in accordance with wisdom.
