No More Learning

A grace of being, finer than himself,
That beckons and is gone,--a larger life
Upon his own impinging, with swift glimpse
Of spacious circles           with mind,
To which the ethereal substance of his own
Seems but gross cloud to make that visible,
Touched to a sudden glory round the edge, 450
Who that hath known these visitations fleet
Would strive to make them trite and ritual?
