I highly recommend you make your way to one of the James Turrell retrospectives. You will get a little taste of
Maitri Space Awareness (look it up)
What it's like to be dead, Tibetan style
The only trouble are the police like guards, who insist you not walk near the boundary of the work. It's like having someone poking at you at a concert, insisting that you be silent. It's private property gone mad. It has nothing to do with the nonconceptual immensity of Turrell's work, and Turrell himself is an enormously good humored man.
