Alas, 'tis true I have gone here and there,
And made my selfe a motley to the view,
Gor'd mine own thoughts, sold cheape what is most deare,
Made old offences of affections new.
Most true it is, that I have look'd on truth,
Asconce and strangely; But by all above,
These blenches gave my heart an other youth,
And worse essaies prov'd thee my best of love,
Now all is done have what shall have no end,
Mine appetite I never more will grinde,
On newer proofe to trie an older friend,
A God in love, to whom I am confin'd.
Then give me welcome, next my heav'n the best,
Even to thy pure and most most loving breast.
There is a lot of conflicting commentary on this poem, mainly around the question of whether it is about acting or about love. Clearly it is about both.
In the first stanza, the poet regrets having made a spectacle of himself (a 'motley to the view'). In part, this can certainly reflect upon the poet's role as an actor, a role considered by Elizabethans to be next in status to that of a beggar, but the words can be more generally interpreted as roistering in ale houses and other places of ill-repute. That the poet knew these places very well is beyond doubt, as he uses scenes from them to great effect in his plays. 'Gor'd mine own thoughts' simply means that the poet padded his thoughts out for public presentation, 'gore' being a dressmaking term for the process of making something appear more substantial than it is.
The second stanza puts forward the idea that though he has committed errors, these very errors have made him see the true value of his relationship with the young man, and, as an added benefit, given a certain youth back to his emotions.
In the third stanza, the poet promises not to sharpen ('grinde') his appetite on fresh meat any more.
Believe it if you will.
