I was intrigued to learn that E.M. Forster took the title of “A Passage To India” from a poem by Walt Whitman, and hunted the poem down.
Wow. I am not a Whitman fan anyway, but this is even worse doggerel than usual.
“Swiftly I shrivel at the thought of God” - well, in my experience it’s often a cold swimming pool that can have that effect.
