I have a translation of the Upanishads done by WB Yeats and Shree Purohit, called "The Ten Principal Upanishads". A passage from this work is quoted at the beginning of the Lagahoo Poems from which "World Without End" is taken. I copy below the 2 quotations that precede the work. (Quite surprising that you picked up on some of the loose threads here!)
"Above the senses are the objects of desire, above the objects of desire, mind; above the mind, intellect; above the intellect, manifest nature. Above manifest nature, the unmanifest seed; above the unmanifest seed, God... beyond him, nothing."
Katha Upanishad, translated by Shree Purohit Swami and W. B.Yeats
"Now is the judgement of this world; now the ruler of this world will be cast out."
Thanks for your mini dissertation on and translation of the mysterious arcana of Hinduism. Always eye- and mind-opening.
Remain in light.
