I am looking for a Southern California 1-2 day Meditation/Relaxation Retreat?
Sort of in the middle of california is Mount Madonna, where they have the UMS annual retreat. Even though they call themselves the University of Metaphysical Sciences, the retreat is pretty much about meditating. It may work just as well to buy a vacation home in Southern California where you don't know anyone, and don't introduce yourself. I know Taylor Morrison sells homes there.
My husband and I are super stressed out and we are looking for a 1-2 day meditation/relaxation retreat. We want to go some place close (within 3 hours of Orange County) and follow a program of meditation/relaxation. Possibly stay over night and do the same thing the next day. No cell phones, computers, interruptions. Any leads would be much appreciated.
Thanks!
