The Natural.

Oh, human!  Abandon your temples, churches, and mosques, and make ye a Pilgrimage.   Leave your all-too-human gods and embark on a quest for true Immortality!  Establish your chapel amongst the birds and the trees, amongst the Beautiful and Lofty.  You are confined to a Human existence, my friend, and have an unquenchable thirst for the Mysterious.

Worship, then, that which is perfectly Unknowable, yet perfectly Apparent--the Natural.
