Reflection is a special sort of activity, and for the most part it is disengaged. To be in the experiencing of some X, doing, feeling, passing from one nexus to another, and then to be aware of doing all that. This much the system seems designed for; there is a dual consciousness that enables you to focus on X and be aware of focusing on X at the same time. Perhaps this is better described as focusing on X reflectively - the reflection is pushed up into the contextual frame within the original experiencing - it is a sort of augmentation or inflexion. The experience happens in its objects but the reflection is inside the place of the mind, or more simply in the head. It doesn't work to take it further than that - to reflect on the reflecting because you have no place to stand apart from both activities. If you had such a position then it would be easy, a position outside the mind and outside the body. Because it happens so rarely it seems as if the concept of your mind, the palpably lived concept of body-mind is fixed in stone. It needs to be both inside the inside of mind and outside the mind. Nothing about this seems impossible - the witnessing views such contortions with amused detachment.
