Thanks for that NS. Yes...it is interesting.
The idea of a transcendent brain is itself self contradictory. The brain is a limited vessel, a piece of flesh that will die some day. The transcendent part is independent of it and is connected to a far bigger consciousness. To realize this, the microscopic sense of individuality needs to be surpassed.
The attempt to understand and explain the transcendent through the material is bound to fail.....though it is a compulsive need felt by the ego mind to retain control.
