Pretty sure what you are noticing is an absence of bodily tension. If so, Congratulatiuons!
Like when you put your hand on the keyboard, you know that the hand is logically connected to your body. But that intuitive sense that you had (but didn't realize you had) about the hand being 'yours' is greatly diminished ?
Here is an old post from my journal to see if it sounds similar...
[quote=DZ's Journal]In my purusit of non-dual states, I have been following advice posted on DhO by End In Sight. Started to notice the subtle non-sensory tensions in the body. I can confirm his assertions that these tensions have something to do with the mind's self-generated illusion of a unified body. And appear responsible for quite a bit of desire and suffering.
My method on releasing it as follows:
Lie down on back
Release the tensions in the feet, like releasing a tightly wound elastic band.
Allow the tensions to dissipate, there is no longer a subtle mental image of the feet, but rather only the sensory preception of them
Move up the body to the legs, releasing tensions the way one would release an elastic band (i.e. after letting go, it releases itself)
If you do this correctly, there will be no intuitive sense that your 'foot' (or any other part of the body) exists outside of your sensual preceptions. Although logically you will know that this is your foot, and your motor coordination remains
If my diagnosis is correct, then this is outside the MCTB model.
But the start of great things in terms of a reduction in suffering
