[4]Know thou that Prakriti and Purusha are both beginningless; and know thou also that all modifications and Gunas are born of Prakriti.
BG 13.20
प्रकृतिं पुरुषं चैव विद्ध्य् अनादी उभाव् अपि / विकारांश् च गुणांश् चैव विद्धि प्रकृतिसम्भवान्
prakṛtiṃ puruṣaṃ caiva viddhy anādī ubhāv api / vikārāṃś ca guṇāṃś caiva viddhi prakṛti-sambhavān
"Prakṛti and Puruṣa are both beginningless — all modifications and the three guṇas are born of prakṛti alone."
