Fiction that illustrates Alan Watts’ myth of the “skin-encapsulated ego”?

Looking for fiction (perhaps broadly speculative), poetry, or short fiction that puts into action or makes intuitive the ways of seeing/being discussed by Alan Watts in “The Book” and his other writings.

There are books like The Dharma Bums which discuss these Eastern ideas more formally, but I’m mostly looking for works that operate alternatively to the illusion of the self, that presume individuals are of rather than in the universe, that presume or make intuitive the organism-environment field or the game of black-and-white, and so on.

Mary Oliver, for instance, gets close to this emphasis on one’s place in the family of things and ceasing the struggle for control.

Any ideas, even tangentially related (e.g. a la Kerouac), would be appreciated.
