Chapter 17 · The Three Kinds of Faith · Krishna said
Bhagavad Gita 17.3 — You are your faith
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 ||
Meaning
O Arjuna, everyone's faith matches their inner nature. A person is made of their faith — as their faith is, so are they.
In today's life
What you truly put your faith in is what shapes you — so choose it with care.
