William Butler Yeats - Anima Mundi (Chap.29) lyrics

Daemon and man are opposites; man pa**es from heterogeneous objects to the simplicity of fire, and the Daemon is drawn to objects because through them he obtains power, the extremity of choice. For only in men's minds can he meet even those in the Condition of Fire who are not of his own kin. He, by using his mediatorial shades, brings man again and again to the place of choice, heightening temptation that the choice may be as final as possible, imposing his own lucidity upon events, leading his victim to whatever among works not impossible is the most difficult. He suffers with man as some firm-souled man suffers with the woman he but loves the better because she is extravagant and fickle. His descending power is neither the winding nor the straight line but zigzag, illuminating the pa**ive and active properties, the tree's two sorts of fruit: it is the sudden lightning, for all his acts of power are instantaneous. We perceive in a pulsation of the artery, and after slowly decline.
