Of Love: A Sonnet

How Love came in, I do not know,
Whether by th'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 every where.
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.
