Analysis of Sonnet XXVIII: Reign In My Thoughts

Reign in my thoughts, fair hand, sweet eye, rare voice:
Possess me whole, my heart's triumvirate;
Yet heavy heart to make so hard a choice,
Of such as spoil thy poor afflicted stated.
For whilst they strive which shall be Lord of all,
All my poor life by them is trodden down;
They all erect their Trophies on my fall,
And yield me nought that gives them their renown.
When back I look, I sigh my freedom past,
And wail the state wherein I present stand,
And see my fortune ever like to last,
Finding me reign'd with such a heavy hand.
What can I do by yield, and yield I do,
And serve all three, and yet they spoil me too.
