What is a leaf? A leaf is boundlessness compressed within a boundless context.

It is boundless because its very existence is an act of a Creator who knows no bounds, who can extrude an endless number of leaves in endless variety out of the nothingness.

It is boundless in design, containing a wisdom that may be studied for endless lifetimes and yet never depleted.

It is boundless in form, for there is nothing about it that can ever be measured and stored with perfect accuracy, nothing of its future that can be predicted with precision.

And it lies within a context that is boundless, the boundless destiny of all creation: that the Unknowable should be made known from its hiding place within a single leaf.
