In his classic Zahir paulo coelho makes an statement "absolute freedom doesn’t exist; what does exist is the freedom to choose anything you like and then commit yourself to that decision" something similar to what Geeta proclaims in very beginning When Arjuna faces confusion over fighting and killing of own family members and looked for help from Krishna , Even before Krishna starts revealing anything he makes it very clear , " Arjuna I will not take decision on your behalf , it is you who will have to take decision and then that decision will be your responsibility , the ownership of that decision will be with you if you think that some one else will take decision on your behalf and you will be spared from the burden of consequences , thats not happening"
This is what freedom in this world means , one can not sit as a victim because one is associated with its surrounding , family , country. These are emotional associations like Arjuna was associated with his brothers , wives , mother , cousins etc so even though in the beginning of battle he is devastated and thinks of renunciation to attain liberation or complete freedom but we all know that he would have not been able to sustain this. Imagine the scene when Arjuna leaves the battle without fighting , their would have been joy on the side of Kaurava's with sheer excitement they would have eliminated rest of the pandava's within few days , What would Arjun do then ? some one who can not see his teachers and uncles in pain would have seen dead bodies of his real brothers , was he so detached with the world that he could have still continued with his meditation .
I doubt if that would have been the case , instead we would have seen another Arjuna - the destroyer force , who would have again picked up his gandiv and hunted down Duryodhan and company in revenge. That's the reasons Krishna asked him to take a decision considering what his duty is (Karma Yoga ) .
Hence it seems to me that the best way of utilising your freedom is to choose what you consider is right , and stand by it with all might. You are free to choose what do you want but you are not free from choices as long as you are surviving in the society , choices have to made at every step . Let no one make those choices for you , people may help but can not take decision on your behalf because the only way to be happy is to know you have complete authority over choice , it is you who has chosen this path and it is you who will finish it .
