Luminous blue spheres are coming up again, this time in and around the knees and elbows...! There seems to be one on either side of each knee, and either side of each elbow. I know that the chakras are just about everywhere in and around the body, although only the seven main ones are usually described in the literature. These blue spheres may be some of the minor chakras.
Their qualities are of... a luminous blue, deep, soft, cool, infinitely quiet allowing any activity.
