Sonnet XL (second): Love's Loadstone

I know not if it be the fancied light
Which every man or more or less doth feel;
Or if the mind and memory reveal
Some other beauty for the heart's delight;

Or if within the soul the vision bright
Of her celestial home once more doth steal,
Drawing our better thoughts with pure appeal
To the true Good above all mortal sight:

This light I long for and unguided seek;
This fire that burns my heart, I cannot find;
Nor know the way, though some one seems to lead.

This, since I saw thee, lady, makes me weak:
A bitter-sweet sways here and there my mind;
And sure I am thine eyes this mischief breed.
