It's interesting to see what's going on with physics these days because they're starting to come out with stuff that sounds remarkably like Buddhism and even more specifically like the ancient Hindu Vedas. Physics isn't necessarily saying the exact same thing but I think eventually it will merge.

Whether it's a fully enlightened Christ or Buddha, or just a more aware Martin Luther King, Kennedy or Gandhi, what did they do with them here? They shoot them, crucify them, and get them out of the way because people are afraid of truth.
When you develop your psychic vision after some meditation, you will be able to see the subtle physical of others, or perhaps yourself. At first you will see it as an aura; eventually you can see the whole subtle physical.
