4. Although mystics say Ultimate Reality is not a thing, they also agree that this emptiness or no-thingness is not a mere vacuum. It is radiant with the Light of Pure Spirit, Primordial Awareness, Buddha Mind, or Consciousness Itself.

He is the Eternal among things that pass away, pure Consciousness of conscious beings. Upanishads (Hindu)

All the Buddhas and all sentient beings are nothing but the One Mind, besides which nothing exists. Huang Po (Buddhist)

The light by which the soul is illumined, in order that it may see and truly understand everything...is God himself. St. Augustine (Christian)

He is the spirit of the cosmos, its hearing, its sight, and its hand. Through Him the cosmos hears, through Him it sees, through Him it speaks, through Him it grasps, through Him it runs. Ibn 'Arabi (Muslim)

Mind comes from this sublime and completely unified source above; it is divided only as it enters into the universe of distinctions. Menahem Nahum (Jewish)
