Verse
पुरुषः प्रकृतिस्थो हि भुङ्क्ते प्रकृतिजान्गुणान् ।कारणं गुणसङ्गोऽस्य सदसद्योनिजन्मसु ॥
puruṣaḥ prakṛtistho hi bhuṅkte prakṛtijānguṇānkāraṇaṃ guṇasaṅgo’sya sadasadyonijanmasu
Purusha involved in Prakriti enjoys the qualities born of Prakriti; attachment to the qualities is the cause of his birth in good and evil wombs.
Gītā 13·22Forcibly the soul, the individual Purusha, is attracted by her qualitative workings and this attraction of her qualities draws him constantly to births of all kinds in which he enjoys the variations and vicissitudes, the good and evil of birth in Nature. But this is only the outward experience of the soul mutable in conception by identification with mutable Nature.
