I think joy and sweetness and affection are a spiritual path. We're here to know God, to love and serve God, and to be blown away by the beauty and miracle of nature. You just have to get rid of so much baggage to be light enough to dance, to sing, to play. You don't have time to carry grudges; you don't have time to cling to the need to be right.
The spiritual life is the uncovering of deeper and deeper levels of joy until that joy that streams from the God-head itself is realized and known in every breath. Every increase in joy is an increase in strength and peace of soul and an increase in all the powers of creativity that reveal life as a divine dance.
