"perseverance is more than mere endurance, and
faith is the currency exchanged .."
love love love it

"No birds take flight over the plains below, where our tribes and notions are destined soon to clash." At first, I thought no birds would fly over the plain because it was sacred ground, but the second part suggests that war is coming, and it is destruction that drives the air-creatures away. Lovely imagery. :)

"Astride my war chariot." That reminds me of Apollo.

"Faith is the currency exchange between the Atman and the phenomenal world." You know, I'm not usually a fan of monetary metaphors, but this one is creative, so I approve. Also, nice touch of Hinduism and/or Buddhism with the word 'Atman.'

"I yearn to be as a great arrow of yew pulled back...on the bow of Brahma." You are the tool of the gods, E.B., and a great one, if I do say so myself. :)

Interesting introduction of philosophical elements. Phenomenal world vs 'Atman', spiritual world. Body vs spirit. Religion vs empircism. A vision of a future battle(field)- but a battle for what? This lingering question gives the poem a quality of challenging the reader, including him in the battle, the struggle for clarity.
The tone of the poem has a tone that, to me, is like the smell of roses, like a drug that throws you into a stunted state of awe-inspired attentiveness. The romantic, almost heroic tone underlining the bravery and perseverance of the lyrical subject, of the future warrior.
