Joy is a gate of Dharma illumination, for with it we abandon all unpleasant things.Delight is a gate of Dharma illumination, for it is the mind of peace and tranquility.
Love and cheerfulness are a gate of Dharma illumination, for they make the mind pure.
Pure mind is a gate of Dharma illumination, for with it there is no defilement.

I half expect to hear him start singing What's So Funny About Peace, Love, and Understanding? any minute now.
