"It becomes long, deep; it widens, extends, narrows. It is a constricted place, a narrowed place, one of the hollowed out places. There are roughened places; there are asperous places. It is frightening, a fearful place, a place of death. It is called a place of death because there is dying. It is a place of darkness; it darkens; it stands ever dark. It stands widemouthed; it is wide-mouthed; it is narrow-mouthed. It has mouths which pass through. I place myself in the cave. I enter the cave."
