Opportunity

I do not know if, climbing some steep hill, 
Through fragrant wooded pass, this glimpse I bought,
Or whether in some mid-day I was caught
To upper air, where visions of God’s will
In pictures to our quickened sense fulfil
His word. But this I saw.
 A path I sought
Through wall of rock. No human fingers wrought
The golden gates which opened sudden, still,
And wide. My fear was hushed by my delight.
Surpassing fair the lands; my path lay plain;
Alas, so spell-bound, feasting on the sight,
I paused, that I but reached the threshold bright,
When, swinging swift, the golden gates again
Were rocky wall, by which I wept in vain.
