After previously stating that actions performed for the Supreme Lord as a matter of duty without desire for rewards do not bind one to samsara or the cycle of birth and death in material existence, Lord Krishna is illustrating how by bathing the body, meditating in the mind, reflecting with the intellect, hearing and narrating about the divine pastimes of the Supreme Lord and such activities are for the purification of the mind and lead to moksa or liberation from material existence.

Lord Krishna describes the activities of karma yoga or prescribed Vedic activities and how they should be performed to achieve purity of mind.

Completely devoid of all cravings for the rewards of one's actions and endeavours even up to desiring entry to svargaloka or the heavenly spheres. Those who have indeed become accomplished in karma yoga or prescribed Vedic activities without desiring rewards simply let their body, mind and senses perform their natural functions as instruments to effect atma-suddhi or self-purification which breaks the bonds of the past deeds which bind the atma to samsara or the cycle of birth and death. Karma yoga should be performed solely for this purpose and not for obtaining heavenly enjoyments in svargaloka.

Lord Krishna elaborating further states that those practising karma yoga or prescribed Vedic activities without desire perform all their actions free from attachment to sense objects and the hankerings for rewards of actions solely for the purification of the mind.
