Paingala Upanishad

I-1. Then indeed Paingala approached Yajnavalkya as a disciple, and, having served him for twelve years, said: Instruct me in regard to the supreme mystery of Aloneness.
I-2. The eminent Yajnavalkya replied: Dear one, in the beginning this indeed existed. It was the eternally free, immutable, everlastingly one, secondless Brahman, full of Truth, Knowledge and Bliss.
I-3. In it existed the primordial and indefinable Prakriti, consisting of Gunas in a state of equipoise, red, white and dark, resembling (the existence of) water, silver, a man and outlines (respectively) in the mirage oyster-shell, a stump and a mirror; what was reflected in it was the Witness Consciousness.
I-4. Having been modified, with the preponderance of Sattva, and named Avyakta (the Unmanifest), it (Prakriti) became the power of concealment. What was reflected in it became God Consciousness. He has Maya under His control, is omniscient, is the initial cause of creation, sustenance and dissolution (of the world) and has the form of the sprouting world. He manifests the entire world dissolved in Him. Due to the power of the Karmas of living beings is the (world) spread out like this cloth and due to their exhaustion again is (the world) concealed. In Him alone does the entire world exist as a folded cloth.
I-5.From the power of concealment controlled by God arose the Power of Projection called Mahat. What is reflected in it is the consciousness of Hiranyagarbha. He has the conceit of ownership as regards Mahat and has a body partly manifest and partly unmanifest.
I-6. From the projective power controlled by Hiranyagarbha arose the gross power called the ego, with the preponderance of Tamas. What was reflected in it was the consciousness of Virat. That Virat who has conceit in the Ego, a manifest body, and is the Chief Person, Vishnu is the protector of all gross things. From that Self (Virat) arose ether; from the ether, air; from air, fire; from fire, water; from water, earth. These five root-elements are composed of the three Gunas.
