Within me, and my mental eye grew large
With such a vast circumference of thought,
That in my vanity I seem'd to stand
Upon the outward verge and bound alone
Of full beatitude. Each failing sense
As with a momentary flash of light
Grew thrillingly distinct and keen. I saw
The smallest grain that dappled the dark Earth,
The indistinctest atom in deep air,
The Moon's white cities, and the opal width
Of her small glowing lakes, her silver heights
Unvisited with dew of vagrant cloud,
And the unsounded, undescended depth
Of her black hollows. The clear Galaxy
Shorn of its hoary lustre, wonderful,
Distinct and vivid with sharp points of light
Blaze within blaze, an unimagin'd depth
And harmony of planet-girded Suns
And moon-encircled planets, wheel in wheel,
Arch'd the wan Sapphire. Nay, the hum of men,
Or other things talking in unknown tongues,
And notes of busy life in distant worlds
Beat like a far wave on my anxious ear.

A maze of piercing, trackless, thrilling thoughts
Involving and embracing each with each
Rapid as fire, inextricably link'd,
Expanding momently with every sight
And sound which struck the palpitating sense,
The issue of strong impulse, hurried through
