Ani, after reading your Cosmic Consciousness post, I saw a few omissions in my post so I   will add a couple notations here:

1) tears

In the emptiness the physical eyes secreted tears. I feel this is related to the concentration. Tears kept slowly rolling down the cheeks every minute or so as if in slow motion. 

2) awareness of the body and what is happening in the external environment.

The “knowing” is the dominant feature and that is a bodiless knowing which was still aware that there was a physical form and an environment around it. Sounds were heard like the birds chirping and the skin also felt sensations (like the tears rolling down the cheeks). However that is all happening at a distance. The inner and the outer are clearly delineated as if being separate realms altogether.

3) I try not to think about it too much or analyze it. It’s pretty much out of my control and I’m grateful to get these shifts whenever they arise.
