Two wedded Hearts, if e'er were such,
Imprison'd in adjoining cells
Across whose thin partition wall
The Builder left one narrow rent,
And there most content in discontent
A Joy with itself at strife,
Die into an intenser Life/

Another Version

The Builder left one narrow rent,
Two wedded Hearts, if e'er were such,
Contented most in discontent
There cling, and try in vain to touch!
O Joy with thy own Joy at Strife,
That yearning for the Realm above
Would'st die into intenser Life,
And union absolute of Love.
[September 1808. From MS]
