It`s hard to explain what`s it: to feel a glass prison.
My normal state is the feeling of extantion as if my unvisible spirit-body let me to touch clouds and stars, my ears can hear more then surrounding sounds, it hears the movement of galaxies higher, higher. In that state my mind contains knowledge how the world growth, and feel many things one time. Amazing state. And sometimes I lost it.
As it happens I feel how a glass prison separates me from all world. Invisible, sound-knowledge-proof prison, a glass box with so small size then my physical body feels pressure, and although I am healthy I started to choke. That time I want to fight with glass walls, but vainly, there is no solid walls. I feel myself in the bottom of deep narrow well. That time I have to control my breath and mind and restrict my thrist to return my original state, or to be out of that game and leave that flat narrow place of dingy colors and limitations.
Yoga and music helps me to relive it. After several hours or several dayes the walls of the glass prison started to thin and disappired as a sugar candy. As Heavens opens my glass prison dissolves until it will be next time.
