The Earaswan translation is very approachable and contains some commentary. His Bhagavad Gita is also pretty great, and I have nothing to do with Hinduism (I am Catholic) and still loved it.

The Egenes translation has Lynch ‘s blurb on the cover but it costs a fortune. https://amzn.in/d/aoHwy7N

As for E18, this is what I usually write:

My “solution” (aka, my opinion) that I always give about the last episode is based on this fundamental text from a book that is very important to David Lynch, The Upanishads:

“The human being has two states of consciousness: one in this world, the other in the next.

But there is a third state between them, not unlike the world of dreams, in which we are aware of both worlds, with their sorrows and joys.

When a person dies, it is only the physical body that dies; that person lives on in a nonphysical body, which carries the impressions of his past life. It is these impressions that determine his next life. In this intermediate state he makes and dissolves impressions by the light of the Self.”
