For mind and body, spirit and matter, have reciprocities of power,
And each keepeth up the strife; a man's works make or mar him.
There be deeper things than these, lying in the twilight of truth;
But few can discern them aright, from surrounding dimness of error.
For perchance, if thou knewest the whole, and largely with comprehensive mind
Couldst read the history of character, the chequered story of a life,
And into the great account, which summeth a mortal's destiny,
Wert to add the forces from without, dragging him this way and that,
And the secret qualities within, grafted on the soul from the womb,
And the might of other men's example, among whom his lot is cast,
