I witnessed the transformation from pure light back into rainbow light as I returned from the out-of-body experience. I entered my physical body through the heart space. It felt like a vast energy field that painted itself in the color green. From the heart space, the energy spread along my spine. It vibrated into different areas of my body, taking on different colors. This was when I became aware of my energy body, and how it is permeated by vibrations that reveal themselves in different colors. The awareness of colors within my body became my foundation for meditation. I discovered energy centers in some regions of my body, and realized, I found access to the chakras.
