BG Chap 18 - Meaning of surrender to Kṛṣṇa

Surrendering unto Kṛṣṇa alone implies there should be no worship of devatās or the practice of aṣṭāṅga yoga, jñana or other forms of dharma. One should not think that surrendering to the Lord would result in the fear that arises from not performing one’s nitya and naimittika karmas. There is no sin in giving up these duties, rather in performing them, one would be committing sin because of disobeying the Lord’s order. There is no sin at all in rejecting dharmas: the sannyāsī renounces the fire sacrifice by the order of Vedas. Similarly, the surrendered soul renounces his duties by the order of the Lord. Thus when the Lord assures that one need not worry (mā sucaḥ) it does not mean one need not worry about the sin incurred for non-performance of duties, but rather one need not worry about not executing niṣkāma karma and jñana as preliminaries for purification. These are not necessary in full surrender.

One should follow the six items of surrender: perform activities pleasing to the Lord; give up activities not pleasing to the Lord; think of the Lord alone as one’s protector; have faith that Lord will protect when one’s existence is threatened or accepting complete dependence on the Lord; employ one’s body and senses in Kṛṣṇa’s service and placing oneself fully to the Lord; and being always humble thinking that no one is more merciful than the Lord and no one is more fallen than us.

One should not worry about one’s position if one follows the Lord and if the Lord engages one in adharma, for the Lord promises to free one from all sinful reactions – past, present and future. The Lord takes the burden of love of freeing the devotee from saṁsāra.

Previously Kṛṣṇa had said that Arjuna was not qualified for ananya bhakti and asked him to be an intermediate devotee in the form of whatever he did should be done as an offering to the lord. Only by the causeless mercy of a pure devotee can one obtain ananya bhakti. But now the Lord is breaking that rule and was bestowing Arjuna pure bhakti Himself.
