Bhagavad Gita 17.3

सत्त्वानुरूपा सर्वस्य श्रद्धा भवति भारत।श्रद्धामयोऽयं पुरुषो यो यच्छ्रद्धः स एव सः॥

sattvānurūpā sarvasya śraddhā bhavati bhārata |śraddhāmayo'yaṃ puruṣo yo yacchraddhaḥ sa eva saḥ ||

The faith of each is in accordance with their nature, O Arjuna. People consist of their faith; as a person's faith is, so are they.

Every person's faith conforms to their nature. By nature, they are full of faith. They are, in fact, what their faith makes them.

Our plain-language meaning of this verse is waiting for scholar review.
