“All that is gold does not glitter,
Not all those who wander are lost;
The old that is strong does not wither,
Deep roots are not reached by the frost.

From the ashes a fire shall be woken,
A light from the shadows shall spring;
Renewed shall be blade that was broken,
The crownless again shall be king.”
― J.R.R. Tolkien, The Fellowship of the Ring

“Humans are amphibians...half spirit and half animal...as spirits they belong to the eternal world, but as animals they inhabit time. This means that while their spirit can be directed to an eternal object, their bodies, passions, and imaginations are in continual change, for to be in time, means to change. Their nearest approach to constancy, therefore, is undulation--the repeated return to a level from which they repeatedly fall back, a series of troughs and peaks.”
― C.S. Lewis, The Screwtape Letters
