The spirit becomes camel, then lion, then child. The camel kneels and asks: “What is the heaviest thing, ye heroes? ...that I may take it upon me and rejoice in my strength.” It bears every load — the craft, the discipline, the years of carrying. In the loneliest wilderness it becomes a lion: “‘Thou shalt,’ is the great dragon called. But the spirit of the lion saith, ‘I will.’” The lion's work is to “give a holy Nay even unto duty” — to kill every inherited rule, including the ones that made the camel strong. And the lion still cannot create: for that it must become a child — “Innocence is the child, and forgetfulness, a new beginning, a game, a self-rolling wheel, a first movement, a holy Yea.”
