Śraddhā-Trayā-Vibhāga Yoga · Verse 2
श्रीभगवानुवाच | त्रिविधा भवति श्रद्धा देहिनां सा स्वभावजा | सात्त्विकी राजसी चैव तामसी चेति तां शृणु
śrī-bhagavān uvāca | tri-vidhā bhavati śraddhā dehināṃ sā svabhāva-jā | sāttvikī rājasī caiva tāmasī ceti tāṃ śṛṇu
Triple is the faith of the embodied, born of their own nature — sāttvika, rājasī, and tāmasī. Listen about it.
Kṛṣṇa answers by establishing the typology. Śraddhā (faith, conviction, trust in the sacred) is tri-vidhā — triple, according to the guṇas.
It is svabhāva-jā — born of the own nature of the dehin (the one who has a body, the jīva). It is not arbitrary but an expression of internal constitution. The three types: sāttvikī (of sattva), rājasī (of rajas), tāmasī (of tamas).
