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.
Should a greater ecological awareness begin to shape our thinking, new symbols would arise that could bind the scientific and the spiritual and would reinfuse all life with the essence of the sacred. We would be increasingly capable of envisioning the "blue, true dream" that is the living Earth luminous in the darkness of the surrounding sky.
