Manly P Hall talks about the goals of many of these High Priest in How to Understand Your Bible:
"One who sleeps, he who is dead, and he who is buried, all are brought back to life - life here representing a condition of spiritual awareness.

In these Mysteries, Jesus stands as the hierophant, and into his mouth are placed the words of the high priest. He is made a personification of the Truth which he represents."
