FREE WILL

Free will is the ability of persons to make choices unconstrained by certain factors. These factors include metaphysical constraints such as logical, nomological, or theological determinism, physical constraints such as chains or imprisonment, social constraints such as threat of punishment or censure, or structural constraints, and mental constraints such as compulsions or phobias, neurological disorders, or genetic predispositions.

In the religious realm, free will implies that individual will and choices can coexist with an omnipotent divinity.  This would be the case with Christianity, for example, but is not so with Vedanta.  Brahman is an omnipotent divinity, in a manner of speaking, but it does not participate in existence.  It only watches existence, witnesses it.

This leaves the constraint of karma.  When a person is born he carries good and bad karma which express themselves as tendencies.  The choices he makes reflect these tendencies, which limit his free will.
