What's So Bad About Joy, Delight and Cheerfulness?

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.

After months of reading Dogen in Zuimonki encouraging his monks to abandon family, society, romance, and matrimony for single-minded pursuit of the Zen life, it's somewhat refreshing to hear him acknowledge, that, yeah, joy and delight and love and cheerfulness aren't necessarily bad things.

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