Some schools say that spiritual Essence is some kind of light. This again does not create any difficulty with the view of Presence. Presence is nothing but the presence of spiritual light; spiritual light can be experienced as a fundamental reality, which has an ontological property. The ontological property of spiritual light is Presence, where light and Presence are not two separate things. By spiritual light, we do not mean the common experience of seeing light in one's psyche. The spiritual light we are referring to is a fundamental light of consciousness and awareness.
