Light is one of the primary metaphors in sacred poetry, suggesting the Divine not framed within a mental concept. But for many genuine mystics, this light is directly experienced.
This sense of light is more than a brightness one might experience on a sunny afternoon. This light is perceived as being a living radiance that permeates everything, everywhere, always. This light is immediately understood to be the true source of all things, the foundation on which the physicality of the material world is built.
The sense of boundaries and separation, long taken for granted by the mind as the fundamental nature of existence, suddenly seems illusory, for this light shines through all people and things. It has no edges, and the light of one is the light of all.
Often, one describes being "bathed" in this light, and that is absolutely fitting. This light is not merely an airy phenomenon of the visual realm; it is tactile, permeating, embracing, profoundly soothing, revitalizing, healing. Some describe it in liquid language: water, fountain, lake, a shining white or golden ocean.
This light is recognized as your own Self, while simultaneously being the Self of all others. Since this light is you and, at the same time, it radiates within all, the question arises: How can there be separation? conflict? loss?
This is the light of the true mystics.
