Famous quotes containing the words thread and/or form:
“It launchd forth filament, filament, filament, out of itself,
Ever unreeling them, ever tirelessly speeding them.
And you O my soul where you stand,
Surrounded, detached, in measureless oceans of space,
Ceaselessly musing, venturing, throwing, seeking the spheres to connect them,
Till the bridge you will need be formd, till the ductile anchor hold,
Till the gossamer thread you fling catch somewhere, O, my soul.”
—Walt Whitman (18191892)
“Falsehood is invariably the child of fear in one form or another.”
—Aleister Crowley (18751947)
