Bhagavad Gita · 13.20

प्रकृतिं पुरुषं चैव विद्ध्यनादी उभावपि।विकारांश्च गुणांश्चैव विद्धि प्रकृतिसम्भवान्॥

prakṛtiṁ puruṣhaṁ chaiva viddhy anādī ubhāv api vikārāṁśh cha guṇāṁśh chaiva viddhi prakṛti-sambhavān

Know that both prakriti (material nature) and purusha (the conscious being) are beginningless. And know that all modifications and qualities are born of prakriti.
