Sometimes a mortal feels in himself Nature, not his Father but his Mother stirs within him, and he becomes immortal with her immortality.

Context

“In the hues of October sunsets, we see the portals to other mansions than those which we occupy, not far off geographically,— “There is a place beyond that flaming hill, From whence the stars their thin appearance shed, A place beyond all place, where never ill, Nor impure thought was ever harbored.” Sometimes a mortal feels in himself Nature, not his Father but his Mother stirs within him, and he becomes immortal with her immortality. From time to time she claims kindredship with us, and some globule from her veins steals up into our own. I am the autumnal sun, With autumn gales my race is run; When will the hazel put forth its flowers, Or the grape ripen under my bowers?” source
