Visualization for Ajna (Third Eye Chakra)
Breath deeply for a few moments. Now imagine that you are sitting comfortably in your home. An intense, deep purple ray of light about the size of your palm shines down from a few feet above you into your head, past your crown chakra, and down into Ajna. The column of light rotates very slowly and there are small flecks of colourless light floating within it.
After a few minutes, a soft violet light begins to emanate from Ajna. This light grows steadily brighter until eventually several beams of light shine out from the centre of the chakra to a point a few feet beyond your head, forming a circle just above the level of your eyes. These beams of beautiful violet light rotate in sync with the dark purple ray shinning down from above.
