Analysis of Sonnet XLV

LEaue lady, in your glasse of christall clene,
Your goodly selfe for euermore to vew:
and in my selfe, my inward selfe I meane,
most liuely lyke behold your semblant trew.
Within my hart, though hardly it can shew,
thing so diuine to vew of earthly eye:
the fayre Idea of your celestiall hew,
and euery part remaines immortally:
And were it not that through your cruelty,
with sorrow dimmed and deformd it were:
the goodly ymage of your visnomy,
clearer then christall would therein appere.
But if your selfe in me ye playne will see,
remoue the cause by which your fayre beames darkned be.
