Of Love: A Sonnet

How love came in I do not know,
Whether by the eye, or ear, or no;
Or whether with the soul it came
(At first) infused with the same;
Whether in part ’tis here or there,
Or, like the soul, whole everywhere,
This troubles me: but I as well
As any other this can tell:
That when from hence she does depart
The outlet then is from the heart.
