A Dialogue of Self and Soul William Butler Yeats

I

My Soul. I summon to the winding ancient stair;
Set all your mind upon the steep ascent,
Upon the broken, crumbling battlement,
Upon the breathless starlit air,
Upon the star that marks the hidden pole;
Fix every wandering thought upon
That quarter where all thought is done:
Who can distinguish darkness from the soul?

My Self. The consecrated blade upon my knees
Is Sato's ancient blade, still as it was,
Still razor-keen, still like a looking-glass
Unspotted by the centuries;
That flowering, silken, old embroidery, torn
From some court-lady's dress and round
The wodden scabbard bound and wound
Can, tattered, still protect, faded adorn.

My Soul. Why should the imagination of a man
Long past his prime remember things that are
Emblematical of love and war?
Think of ancestral night that can,
If but imagination scorn the earth
And intellect is wandering
To this and that and t'other thing,
Deliver from the crime of death and birth.
