Sorry about slow reply... Different time zones.
Dark Uncle summed it up well. It's not a game. I usually tell people it's like the first Matrix film. Make sure you fully understand the consequences of your actions. My personal experience has been the most illuminating life changing but also the most terrifying. Ever read the Tibetan Book of the Dead?
I would never want to "go back" to my old life/self but man some times in the last few years I truly thought I had lost it.
As others have noted this journey is more of a self exploration but there are benign forces we are able to attract, no doubt.
That's why I enjoy reading Carl Jung. He went there himself and emerged a completely different individual. All in the early 20th century!!!
