[souls]

The quote is from Catherine Earnshaw in  Chapter IX  of Emily Brontë's Wuthering Heights, and it is actually "Whatever our souls are made of, his and mine are the same, and Linton's is as different as a moonbeam from lightning, or frost from fire." So i took artistic license and changed it a bit ;) 

We know it’s love that keeps a love secure,

And only by love of love can love endure,

For self’s a killer, reckless of the cost,

And loves of lilactime unloved are lost.

We build our altar, then, to love and keep

The holy flame alight and never sleep:

This darling love shall deepen year by year,

And dearer shall we grow who are so dear.

........

This splendour is upon us, high and pure

As heaven: and we swear it shall endure: 

Swear fortitude for pain and faith for tears

To hold our shining barrier down the years.
