As our internal experience versus the outside world seems to be the source of this mind brain conundrum, what evidence do we have that our experiences in any way are non-physical? It is interesting that spiritual concepts have to be described using physical concepts, like space, light, because we cannot otherwise describe that which we conceive of as being formless. We give formlessness pretend qualities so we can talk about it, but it is always beating around the bush trying to scare up something we cannot grasp. Now look what happens with meditation. People experience different stages in the way they experience the world. Different systems describe various kinds of experience, but they tend to boil down to just a few scenarios. The experience of activity, the experience of inactivity (stillness, pure consciousness), the experience of activity and stillness, and the experience where that experience of activity and stillness have merged. (I have left out visions, which are perhaps waking dreams) When experience of activity and stillness have merged, it is no longer possible to say they are different from one another. Thus the physical world and what we call consciousness no longer are distinct in any way: they are the same. This solves the mind/brain problem experientially because it no longer makes any sense to assume there is a physical *and* a metaphysical dimension to life; they simply are one and the same ('the world is Brahman' in Hindu, Vedic terminology), and speculation about the nature of reality from the experiential perspective simply no longer is relevant because one experiences the world as relationship, connectedness, rather than cause and effect. >From a scientific perspective though, there will always be something to >discover, but here too advanced sciences are about relationship, not cause and >effect.

Perhaps the reasons for the debate regarding mind and brain are psychological rather than having anything to do with the reality of the situation. Suppose, hypothetically, that a concrete proof were possible that showed mind and brain were identical in every way and physical. What would that do for you psychologically? And if one were a die-hard empiricist, and the converse was possible to prove, what would that do for you?
