The Camel, the Lion and the Child

In Thus Spake Zarathustra, Nietzsche brings up the following transformation: from camel to lion and then child.

THREE METAMORPHOSES OF the spirit do I designate to you:
how the spirit becometh a camel, the camel a lion, and
the lion at last a child.

First there is the camel.

What is heavy? so asketh the load-bearing spirit; then
kneeleth it down like the camel, and wanteth to be well
laden.

Then the lion.

But in the loneliest wilderness happeneth the second
metamorphosis: here the spirit becometh a lion; freedom
will it capture, and lordship in its own wilderness.
Its last Lord it here seeketh: hostile will it be to him,
and to its last God; for victory will it struggle with the
great dragon [the name of the dragon, "Thou shalt].

And then finally the child.

But tell me, my brethren, what the child can do, which
even the lion could not do? Why hath the preying lion still
to become a child?

Innocence is the child, and forgetfulness, a new beginning,
a game, a self-rolling wheel, a first movement, a
holy Yea.

Aye, for the game of creating, my brethren, there is
needed a holy Yea unto life: its own will, willeth now the
spirit; his own world winneth the world’s outcast.
