The concept of free is like planting a flower in the sky. It does exist in conception but in reality it is not.
We take for example, the Jiva who is defined as an eternal servant of God, whether Direct or Indirectly. When talking about servant, automatically the issue of Master crops up, and when there is a master, then how come there can be a free will.
The depth of this issue can be sensed more and more depending on the level of self-realisation. When a person, be it a Hard Core atheist commits a well chosen free actions, the resultant effects be it +ve or -ve is subsquently imposed on him. The latter might think, I'm free to do this and that, but still hapiness and miseries of life will be waiting to cross his way.
Now, if someone is not agreeing with me, then tell me, who has ever been spared from the four miseries of life(birth, death, old age and disease).
Those who has transcended the dualities of life perfectly understand that no one is independent of God.
