This poem comes from Autumn Leaves:

Seek not for that which is not,

Nor ever was.

Follow not after lies

Or man-made cause.

Seek out truth and

“Peace be still.”

Let your heart and soul

Be filled.

Seek for that which was

And still is.

Love and Life  —

Both are His.

More precious than the Rubaiyat

of Omar Khayyam.

Seek and find the one

And only true “I AM.”
