Bhagavad Gita · 18.66

सर्वधर्मान्परित्यज्य मामेकं शरणं व्रज।अहं त्वा सर्वपापेभ्यो मोक्षयिष्यामि मा शुचः॥

sarva-dharmān parityajya mām ekaṁ śharaṇaṁ vraja ahaṁ tvā sarva-pāpebhyo mokṣhayiṣhyāmi mā śhuchaḥ

Abandoning all dharmas, take refuge in Me alone. I shall liberate you from all sins; do not grieve.
