Mbh 12.342.4a

"'The holy one said, "In the Rigveda, in the Yajurveda, in the Atharvans and the Samans, in the Puranas and the Upanishads, as also in the treatises on Astrology, O Arjuna, in the Sankhya scriptures, in the Yoga scriptures, and in the treatises also on the Science of Life, many are the names that have been mentioned by the great Rishis. Some of those names are derivable from my attributes and some of them relate to my acts. Do thou hear, with concentrated attention, O sinless one, what the import is of each of those names (in particular) that have reference to my acts. I shall recite them to you. It is said that in days of yore you were half my body. Salutations unto Him of great glory, Him, viz., that is the Supreme Soul of all embodied creatures.[1850] Salutations unto Narayana, unto Him that is identifiable with the universe, unto Him that transcends the three (primal) attributes (of Sattwa, Rajas and Minas), unto Him that is, again, the Soul of those attributes. From His grace hath arisen Brahman and from His wrath hath arisen Rudra. He is the source whence have sprung all mobile and immobile creatures. O foremost of all persons endued with Sattwa, the attribute of Sattwa consists of the eight and ten qualities.[1851] That attribute is Supreme Nature having for her soul the Sky and Earth and succeeding by her creative forces in upholding the universe. That Nature is identical with the fruit of all acts (in the form of the diverse regions of felicity to which creatures attain through their acts). She is also the pure Chit. She is immortal, and invincible, and is called the Soul of the universe. From her flows all the modifications of both Creation and Destruction. (She is identical with my Prakriti or Nature). Divested of sex, She or He is the penances that people undergo. He is both the sacrifice that is performed and the sacrificer that performs the sacrifice. He is the ancient and the infinite Purusha.
