Reading that made me think of this passage from Watts….

But now, a perfectly logical person would therefore say that the notion of the Self—the Ātman, as the fundamental reality in which everything else exists—is meaningless. And, of course, from a logical point of view it is.

But at the same time, just because something cannot be put into a logical category does not indicate that it isn’t real. The Self, you see, bears somewhat the same relationship to the world as the diaphragm of the speaker in this radio bears to the music you’ve just been hearing. None of the music was about the diaphragm and nobody said anything about there being a diaphragm. The diaphragm, as such, didn’t come into the picture, and yet it was everything in the picture. All those different noises were vibrations of this thin film of metal. So, also, with your eardrum. So, also, with the apparatus of your eyes.

So one might ask, then—just as you say, “Well, what is it on? What is the music on? Is it on tape, is it on a speaker, is it on a drum?” Whatever the variations may be, we can ask the question, “What are you all on? What is all this on?” And the Hindus answer, “It’s on the Self”
