How does Madhvacharya interpret Bhagavad Gita sloka 18.66?
18.66 sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi mā śucaḥ
Abandon all varieties of religion and just surrender unto Me. I shall deliver you from all sinful reactions. Do not fear.
For example, here is how Ramanujacharya interprets it in his Bhagavad Gita commentary:
'Relinquishing all Dharmas’ — means the complete abandonment of the notion of agency, proprietorship, results etc., in the practice of Karma, Jñāna and Bhakti Yogas which are the means (dharmas) for attaining the highest good when done as Divine Service.
'I will release you from all sins' — means that I will free you from all obstacles that prevent you from attaining Me; consisting of [the karmic reaction of] innumerable acts of doing what is forbidden and neglecting what is bidden. Accumulating from beginingless times [the reactions of] these deeds cause obstacles in spiritual development.
