"To heal is to make happy. I have told you to think how many opportunities you have had to gladden yourself, and how many you have refused. This is the same as telling you that you have refused to heal yourself. The light that belongs to you is the light of joy. Radiance is not associated with sorrow. Joy calls forth an integrated willingness to share it, and promotes the mind's natural impulse to respond as one. Those who attempt to heal without being wholly joyous themselves call forth different kinds of responses at the same time, and thus deprive others of the joy of responding wholeheartedly."
