Asaktabuddhih sarvatra jitaatmaa vigatasprihah;
Naishkarmyasiddhim paramaam sannyaasenaadhigacchati.
He whose intellect is unattached everywhere, who has subdued his self, from whom desire has fled,—
he by renunciation attains the supreme state of freedom from action.
This shloka talks about the person who sets himself free from actions. We ourselves choose actions and we only want to get freedom from the actions. All this is a part of the journey of life. Lord says, a person who wants freedom from actions never allows his intellect to influence any person or any object. He also keeps himself subdued from all those things that create various unwanted desires in him. With all this is a person renounces the fruits of the action and then the action itself, such kind of person is said to have attained freedom from actions.
There is a boat on the surface of water and there is a bridge above the water. A boat is used to cross the river and even a bridge is used to cross the river. A person travelling in the boat has to do nothing but remain static and allow the boat which is in motion to cross the river, while the person who uses the bridge has to take the efforts all by himself and cross the bridge. Here the bridge will be static and the person is in motion. Attachment here is like the boat and the bridge, water is like the desires and the person is the action.
A person who sits on the boat as he is static, experiences the turbulence of boat as he is constantly attached to the movement of boat. But a person who crosses the bridge doesnt bother about the water underneath and quietly crosses it. In life also a person who is unattached to work will not bother about anything and does his work, whereas the person sitting on a boat is constantly worried about how boat manages the turbulence of water. This also teaches an important lesson in life that we should never get attached to anything we do and keep a distance from the fruits of actions just like how bridge keeps a distance from water. That is the secret for getting freedom from actions.
