I found it...
http://en.wikipedia.org/wiki/Turiya
"Turiya is not that which is conscious of the inner (subjective) world, nor that which is conscious of the outer (objective) world, nor that which is conscious of both, nor that which is a mass of consciousness. It is not simple consciousness nor is It unconsciousness.
It is unperceived, unrelated, incomprehensible, uninferable, unthinkable and indescribable. The essence of the Consciousness manifesting as the self in the three states, It is the cessation of all phenomena;
It is all peace, all bliss and non—dual. This is what is known as the Fourth (Turiya).
This is Atman and this has to be realized"
However, after talking to a senior guy, I was told that Human beings are designed with two conscious systems like two Hemisphere of the brain. One is the walking state and the other one is the cloud system where the spirit hangs around next to the body which is entirely separate which I may call subconscious. Because the Hindu issues are between last major space fairing civilization and Now, the items listed in the puranas are not exactly what it is supposed to be.
It is the same issue with Gita. The items were described by Lord Krishna verbally via subconscious (the wi-fi route) to whoever wrote the story and not direct contact. That is because, I think, direct contact at 12,300 years did not have a mechanism to transcribe it - while he was there. Besides, at the time, Krishna group were fighting the alien beings. That is the whole story about Mahabharata.
Best way to find out is to wait till Lord Krishna comes back in about 300 years. Then it can come down to us from the mountain. This is a future projection like everything in the Universe happens...quantum probabilities.
I figure and put it somewhere in sciforums is that we are a four dimensional being. That is what the Universe does to have a better survival and growth. You know, there are many Universes and they each last about a Trillion Years. So, it is better to be a four dimensional than 3 dimensional. It sounds logical and someday science will verify that. Sanatana Dharma did figure that out.
By the way, our ancestors do visit Facebook and Google and read books and watch current Movies....there are ways to find out yourselves....Thank you.
