Bhagavad Gita 17.2
श्री भगवानुवाच · śrī bhagavānuvāca
त्रिविधा भवति श्रद्धा देहिनां सा स्वभावजा।सात्त्विकी राजसी चैव तामसी चेति तां श्रृणु॥
trividhā bhavati śraddhā dehināṃ sā svabhāvajā |sāttvikī rājasī caiva tāmasī ceti tāṃ śrṛṇu ||
The Blessed Lord said, "There are threefold faiths inherent in the nature of the embodied: the sattvic (pure), the rajasic (passionate), and the tamasic (dark). Hear of them."
Lord Shri Krishna replied: Man has an inherent faith in one or another of the qualities—purity, passion, and ignorance. Now, listen.
Our plain-language meaning of this verse is waiting for scholar review.
