The Yoga of Light -- Introduction to Inner Light Meditation

"If your eye be Single, your whole body will be full of Light." (Yeshua​) "In the center behind and above the eyes there is an aperture; on this side of it is the material world, in which we are living now; and on the other side is the astral world." (Sawan Singh) "The inner Light does not come or go. It is always there within. It appears only when we are attuned and concentrated and disappears as soon as there is the slightest dispersion. The Light will not vanish if you just keep your inner gaze constantly fixed." (Kirpal Singh) "Look within yourself with the inner eye. The whole expanse inside is replete with the refulgence of the Divine Light." (Dadu)
