Therefore think not the Past is wise alone,
For Yesterday knows nothing of the Best,
And thou shalt love it only as the nest
Whence glory-wingèd things to Heaven have flown:
To the great Soul only are all things known;
Present and future are to her as past,
While she in glorious madness doth forecast
That perfect bud, which seems a flower full-blown
To each new Prophet, and yet always opes
Fuller and fuller with each day and hour,
Heartening the soul with odor of fresh hopes,
And longings high, and gushings of wide power,
Yet never is or shall be fully blown
Save in the forethought of the Eternal One.
