A Coat

I

DE my song a

Covered with

Out of old

From heel to throat;

But the fools caught it,

Wore it in the world's

As though they'd wrought it.

Song, let them take it,

For there's more

In walking naked.

On google,

I found this about Yeats:

Yeats was fascinated by the occult and mysticism.

He joined the Golden Dawn, a secret society which practiced ritual magic, in 1890, progressing to its Inner Order in 1893, and remained an active member for most of his life.

He also joined paranormal research organisation The Ghost Club in 191.
