Nature Porn (and reflections).

This is where the bunny went, of course.

The riddle in the trees tells us about the natural order.  They reflect our own blueprint of society.  Some leaves grow lower on the tree (whether they wanted to or not, that's where they ended up sprouting).  There, it is nearer to the earth, it's cooler, shadier, lets call this the mineral realm.

The mineral realm sees the nuts the bolts, the reality of the soil.  They devote their energies to relaying the water on down to the roots.  The roots that feed itself as well as all the other leaves on the tree--whether light, dark, withered, broken, hole-y, unholy, striped, purple, etc.  That is the mineral realm.  They have the responsibility of choosing the best seeds to water in the soil.  They have to flesh through the bits of pollutants in the soil and water in order to fuse the two most efficiently.  This is the mind and body coming together through the elements, a cyclical, dual-nourishment.

Velveteen leafies

The leaves on the top are in the light realm--bodily absorption of the elements.  They protruded for a reason--showering themselves in light is just their nature.  It's what they must do to survive and for the survival of the ones below that can't reach enough light.  By absorbing light themselves, performing their duty to its greatest extent given its position in the light, the benefits flow to the rest .
 Some leaves give too much of themselves, trying to take in more light than their veins can handle.  They grow up fast, live fast, perform their duty to its max efficiency plus ten (absorbing light), and then dry up and crackle away.  Similarly, as a human lives fast, so does it dry faster.  It is depleting its physical form at a faster pace than those with a balance of light and shade.

Architecturally sound.

Like any mental formation that people make about their lives--they MUST do this or MUST do that to survive.  The ones that go to extremes exert themselves unnecessarily, but feel a sense of duty and altruism for doing so.  And Sometimes the other leaves are kind enough to grow up too, take responsibility, and shade the former from the intensity of light.  The torch gets passed.  The shadows passed down to the middle--trickling down into darkness- minerals in the soil.
