Bhagavad-gītā As It Is · Text 14.5
How goodness, passion and ignorance bind
सत्त्वं रजस्तम इति गुणा: प्रकृतिसम्भवा: ।
निबध्नन्ति महाबाहो देहे देहिनमव्ययम् ॥ ५ ॥
sattvaṁ rajas tama iti
guṇāḥ prakṛti-sambhavāḥ
nibadhnanti mahā-bāho
dehe dehinam avyayam
Translation
Material nature consists of three modes – goodness, passion and ignorance. When the eternal living entity comes in contact with nature, O mighty-armed Arjuna, he becomes conditioned by these modes.
