There was a quote I heard one time in a Dan Millman (dood who wrote that Way of the Peaceful Warrior book) lecture that has stuck with me. He says that one day after giving a talk a man approached him and said "You know Dan I really wanted to start a spiritual practice but "real life" kept getting in the way, I'd have to go to work and pay bills and be with my family... It wasn't till much later I realized that this "real life" was my spiritual practice, and it demanded more and developed more than just sitting off in a cave somewhere and meditating."

I'd suggest that the process and purpose of the all important integration phase of the psychedelic experience is in how we take the lessons of these powerful experiences and utilize them to walk through our day to day living in a moar humble, moar kind, moar conscious, and yes perhaps even moar sacred manner.
