Mysterious poem

A relative found this poem written inside the back cover of her copy of George Bernard Shaw’s The Adventures of the Black Girl in Her Search for God (and Some Lesser Tales), and wondered if anyone can identify its origin? There is no other inscription on or in the book.

Strangers all……
But to me
Must fall
Odd romances
Of words
and passions
and strange 
“Tis not all”
The Devil
“But more?”
I pray not……
To lose all
Till end of Tyme?
