Bhagavad Gita Chapter 5.17
tad-buddhayas tad-ātmānas
tan-niṣṭhās tat-parāyaṇāḥ
gacchanty apunar-āvṛttiḿ
jñāna-nirdhūta-kalmaṣāḥ
Translation
When one’s intelligence, mind, faith and refuge are all fixed in the Supreme, then one becomes fully cleansed of misgivings through complete knowledge and thus proceeds straight on the path of liberation.
