प्रकृतिं पुरुषं चैव विद्ध्यनादी उभावपि ।विकारांश्च गुणांश्चैव विद्धि प्रकृतिसम्भवान् ॥
prakṛtiṃ puruṣaṃ caiva viddhyanādī ubhāvapivikārāṃśca guṇāṃścaiva viddhi prakṛtisambhavān
Know thou that Purusha (the Soul) and Prakriti (Nature) are both without origin and eternal; but the modes of Nature and the lower forms she assumes to our conscious experience have an origin in Prakriti (in the transactions of these two entities).
Gītā 13·20The Soul and Nature are only two aspects of the eternal Brahman, an apparent duality which founds the operations of his universal existence. The Soul is without origin and eternal, Nature too is without origin and eternal; but the modes of Nature and the lower forms she assumes to our conscious experience have an origin in the transactions of these two entities.
