Lord Krishna says in chapter four that actions renounced through transcendental wisdom do not create reactions:
Yogsanyastkarmarham gyansanchhinsanshayam I
Atamvantam na karmarhi nibandhanti dhananjaya II (4.41)
Therefore, one who has renounced the fruits of his actions, whose doubts are destroyed by transcendental knowledge and who are firmly situated in self, is not bound by works, Oh conqueror of wealth!
Lord stresses on devotion whereby one attains yoga of seeing sameness, there is nothing else than the Lord himself in every inanimate and animate aspects of life.
Self Soul like Super Soul is action less. The embodied self soul having identified with mind body set through mental speculation creates ego of body. Whatever reactions come out of previous assumptions of identification, they are natural reactions. Every action of embodiment is liberating.
Reactions are not binding.
What is binding is our identification with those reactions and desire for fruits from them. An Embodiment has right to undergo reactions but it has no right to desire fruits for these reactions.
It is identification like that one which may come in time while seeing a picture running of film screen.
There may come scene of suffering or achievement on film scene. But film goers have no impact. If they identify with the character of film or his happiness or distress in mind, it is their foolishness. This is exactly what we do. The embodiment is meant to undergo action like a film and we have to refrain from identifying with scene coming in life.
Bodies may die or born. Onlooker has no effect.
This is wisdom.
Lord Krishna says in chapter that there is no faculty without his presence. Divine Self Souls are actor in divine play.
In chapter 9 verse 16 to 19 the Lord Krishna himself reveals
Aham karturaham yagya swadhaahamaham aushadham I
Mantroahamahamevajyaahamagniraham hutam II
Pitaahamasya jagto mata dhata pitamahaah i
Vaidyam pavitramonkaram riksam yajurevch II
Gatirbharta parbhu sakshi niwasah sharnam suhrit I
Pabhavah parlayah sathanam nidhanam beejamavayayam II
Tapamiahamaham varsham nigraharhamiutsrijyamich I
Amrit chev mritushch sadasadchahamArjun II (9.16-19)
I am ritual, I am sacrifice, I am offering, I am food grains, I am Vedic verse. I am purified butter I am sacred fire and I am act of oblation.
I am father, mother, grand father, sustainer and ruler of this world, one worth knowing, purifier, the sacred syllable OM and three vedas rik ,sam and yaju.
I am supreme goal, supporter, Lord, witness, abode, refuge, well wisher, origin and end, resting place, store house and imperishable seed of all.
Arjun! I radiate heat as Sun, hold back and send showers, I am immorality as well as death; I am truth and untruth too.
Thus the devotee sees almighty supreme self in the whole of universe, in every minute and sublime.
This makes a devotee see the kindness of Lord in every pleasant and odd situation. He is detached from the results of the natural action he has to undergo by dint of his past attachment with deeds now resulting in actions.
Thus detaching himself from the actions, not longing for results of actions, all doubts dispelled by transcendental knowledge, completely absorbed in the self, this devotee is free from bondage caused by attachment.
