4.23 Of a person whose attachment to all objects is gone because of his mind being established in the knowledge of the self, who is therefore liberated from accepting all worldly possessions and who is engaged in the performance of sacrifices etc., as described above - in the case of such a person his beginningless load of Karma, which is the cause of his bondgae, is completely dissolved, i.e., destroyed without leaving any residue.

So far the nature of Karma as having the form of knowledge has been described as emerging from constant contemplation on the nature of the self as different from Prakrti. And now Sri Krsna says that all actions together with their ancillaries, have the form of knowledge because of constant contemplation by the aspirant on the Supreme Person who is the Supreme Brahman, as being his soul.
