Itís just that Iím wondering if the darkness we see when we close our eyes, is seen by the physical eyes or not. Iím guessing it is seen by the physical eyes, as when we close our eyes in a lit room we see no darkness only grey, due to the light of the room not allowing us to see complete darkness behind our eyelids, which are allowing some light in.
My problem is, that whilst I take everyoneís word that the 3D blackness is not seen by the physical eyes, I donít understand how one can get to that stage phasing in a lit room, when the eyelids are still letting some light in, and so not allowing the complete blackness needed in order to start noticing things in that blackness; the noticing of which, will, I imagine, lead to the 3D blackness experience.
For me, itís a question of how to get there in a lit room. Not that I have to use a lit room. Itís just a question that has been bugging me.
My understanding is that the initial darkness you see is physical.
The 3D darkness is not physical. 3D darkness is the lack of physical visual input.
