The question of why ‘awareness’ has a perspective, why is it not free to roam, so that now it is seeing things from the perspective of your physical body, and now seeing things from the perspective of my physical body, is an explosion of phantasms of conceptual ideas littering your understanding. However, the major oversight is not seeing that your question assumes that non-individuated awareness would be all-perceiving. Why must that be? Isn’t this just the concept of God reemerging, but now called ‘awareness’?
In Buddhist philosophy there is no God. Why then rename God “awareness”?
It is a basic, but profound insight that there is nothing that endures permanently, and thus nothing that has an intrinsic self. Therefore our ‘physical’ bodies are constructions of our mind. This does not mean that there isn’t the appearance of a body, it means that the appearance of a body is conceptually structured. Why then fail to see that we are simply transferring the independent selfhood and permanence of existence of our naïve understanding to ‘awareness’?
But there is another taint in the framing of this question. You are assuming that this ‘awareness’ is basically a ‘seeing’ of what it is aware of. But this is just our naïve understanding put into a new box labeled “awareness.” It’s carrying an important misunderstanding forward in a different guise. Change it slightly and perhaps we can make this misunderstanding more uncomfortable to live with: let’s assume that ‘awareness’ doesn’t see, it hears. This means there is no perspective from your body, and none from mine. Sound pervades all directions, and so as long as we are standing near each other, ‘awareness’ will hear the same thing. But it won’t know what anything looks like. It will be like a blind man.
Let’s go a step further: the blind man goes deaf. Why, after all, is this ‘awareness’ framed as a perceiving, when what we really need it to be is a knowing. That is why we abstracted it out of ‘our’ experience and made it something separate from what is experienced, after all. But if it is a knowing, rather than a perceiving, how does it know, if it is something other than what is happening?
I leave you with that to ponder.
In my own case, I came to the insight that knowing is not different than appearing, and thus, ‘awareness’ knows by doing, not perceiving. And because of this, ‘my’ ‘awareness’ is locked into my body because that’s what it’s doing. And similarly for ‘your’ ‘awareness’.
Take out the imputed self-identities of ‘me’ and ‘you’, and the conceptual image of an all-perceiving ‘God’, and you’re getting close to the truth.
