It was a pillar so held to be true,
it was a pillar which i held fast to as the first scouts of the storm arrived,
it was a pillar whose shadow i glimpsed in the sunlight and whose mass i felt in the dark
it was a pillar of a nature i knew not and of a source i knew less still,
it was a pillar which did as i pleased and grew with my mind
and as the uncertainty loomed large,it melted away,now i think it's gone,and i shall grope carelessly for a mainstay.
