Bhagavad Gita 18.66
Give up your earthly duties, surrender yourself to Me alone. Do not be anxious; I will absolve you from all your sins.
सर्वधर्मान्परित्यज्य मामेकं शरणं व्रज।अहं त्वा सर्वपापेभ्यो मोक्षयिष्यामि मा शुचः॥sarvadharmānparityajya māmekaṃ śaraṇaṃ vraja|ahaṃ tvā sarvapāpebhyo mokṣayiṣyāmi mā śucaḥ||
