Kṛṣṇa is a great science. So if we study Kṛṣṇa science with great attention, then the result will be that we shall be free from the reaction of our activities. This is clearly said here, na mam karmāṇi limpanti na me karma-phale spṛhā (BG 4.14). The Lord has nothing to do. He is full. He has nothing to do. But why He does? Just to set example. Set example. He's not bound up by the works which He is doing in the material world. This science has to be learned. Na me karma-phale spṛhā. And anyone who understands this transcendental nature of Kṛṣṇa, he is also becoming free from the reaction of karma.
- evaṁ jñātvā kṛtaṁ karma
- pūrvair api mumukṣubhiḥ
- kuru karmaiva tasmāt tvaṁ
- pūrvaiḥ pūrvataraṁ kṛtam
Now, the whole spiritual process is to follow the example of the previous ācāryas who have attained, I mean to, success... (boys making noise outside) These boys, wherefrom they come? They disturb...
- evaṁ jñātvā kṛtaṁ karma
- pūrvair api mumukṣubhiḥ
- kuru karmaiva tasmāt tvaṁ
- pūrvaiḥ pūrvataraṁ kṛtam
Now, there are, Arjuna... Kṛṣṇa is advising Arjuna that "If you act and follow in the footprints of the previous ācāryas and previous great devotees and kings who have done in their lives karma-yoga, acting for Kṛṣṇa, if you follow that principle, then you shall also become free from the reaction of activities." Because Arjuna was very much afraid for being entangled in the reaction of his fighting, Kṛṣṇa therefore assures that "You shall not be... If you follow, if you act, if you fight for My sake, then you will not be entangled by the reaction of karma."
