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

The carama-śloka (final verse) of the BG — supreme synthesis. Sarva-dharmān parityajya — abandoning all dharmas (duties, even sva-dharma).

Mām ekaṃ śaraṇaṃ vraja — to Me alone, take refuge. Ahaṃ tvāṃ sarva-pāpebhyaḥ mokṣayiṣyāmi — I shall liberate you from all sins. Mā śucaḥ — do not grieve, do not fear.

Total śaraṇāgati — absolute surrender to the Divine who saves.
