I liked this. Spelunking - underground, references to Greek Mythology, Some corollaries with rites of initiation, the subconscious...we've a similar cast of mind, only the author is a little more articulate.
I've come to a few conclusions. Anything underground is subconscious. And very often it's part of the larger mythology of death and rebirth - Orpheus and Theseus, to go underground is to die and be reborn, and we share a few of the same conclusions...
