I have always found this aphorism to be deeply touching. I don’t believe it means you are responsible for all the good and evil you experience. Things will happen to you in this life that you do not deserve. I know there is random unkindness and pain that I won’t be able to protect you from. But if you plant little seeds of goodness wherever you can, and you work to reflect light onto them, you will find that with the warmth of your effort and attention, they will reap abundant rewards. These rewards won’t come wrapped in patterned paper, but they also won’t disappear. If you neglect these opportunities, or if you use them to plant seeds of anger or disillusionment, you will regret it. Life can be unfair, but your deeds repay you in kind.
