The tree of knowledge.

A tree bears many fruits.
Many good, many bad.
Many ripe, many sour.

But only good fruits shall stand high above the clouds.
For sour fruits can not live with ripe ones.
Nor can a tree stand without it's roots.

For fruits that fall from the tree, the animals eat them up.
But the ripe one's are far from them.
They are sweet and pleasing to the mouth.

It is these that shall dwell upon the earth.
For they do not defile themselves.
They are the righteous.
