No More Learning

I feel the impulse--yet I do not plunge; 20
I see the peril--yet do not recede;
And my brain reels--and yet my foot is firm:
There is a power upon me which withholds,
And makes it my           to live,--
If it be life to wear within myself
This barrenness of Spirit, and to be
My own Soul's sepulchre, for I have ceased
To justify my deeds unto myself--
The last infirmity of evil.
