The experience of being in extreme darkness and then suddenly being immersed and bathed in a total bright light of spiritual energy can be a profound and memorable experience.
This technique of being immersed in total darkness and then suddenly having the entire room filled with radiant bright light was a method used by ancient cultures for spiritual awareness and communication. Cultures, such as the ancient Native Americans, would journey to places like Chaco Canyon and engage in activities that would create spiritual experiences. For example, they would go into pitch-black dark windowless chambers and in those rooms engage in spiritual rites, one being bringing in radiant spiritual light that would fill the entire chamber. It was NOT an artificial light. It was spiritual energy and an energy frequency or vibration of the 7th chakra energy. This is the energy which can connect someone with the Tao. When the moment is right (such as the chakras being cleared, balanced, and aligned) it is possible to expand that energy and have it fill the entire space one is physically in.
I once had this type of experience of being in a totally dark room and then having it suddenly becoming filled with white radiant light. It was totally unexpected and very powerful. It occurred in the middle of the night when I was meditating. I had my eyes shut and suddenly saw a bright white light filling the entire room. At first I thought I was just imagining this so I opened my eyes and the brightness was still there, filling the entire room. I was aware I was not “seeing” this with my physical eyes but experiencing it with my whole energetic self.
Since that experience I began to meditate more during the middle of the night or at least when it was dark. I noticed a difference in the atmosphere and how I felt when I meditated in the dark. It is as if all the filters or imagined obstacles are now shut down and the connections to other dimensions or with spiritual beings was almost effortless. I also started to do my remote Qigong healing treatments in the middle of the night, too, and this too became easier during that dark window of time.
If you have never tried meditating after sunset or before sunrise, give it a try and see what happens.
