The Ajna Light directly mediates with the unconscious mind and the neurophysiology of the body.
Light flicker frequencies entrain brainwaves, bringing you into a relaxed and meditative state. If you are stressed or have a busy mind, even with your thoughts active while the light sequence is playing, you will automatically be brought into a more relaxed state.
There is no need to try to stop your thoughts, just observe your sensations during the session. The Ajna Light assists you to enter a meditative state without years of meditative practice.
