Freedom implies a lack of restriction or restraint in choice of using ones will which is not the case as we are limited on multiple levels of what we may choose and why we may choose it. We are bound to environment and a state of duality in everything, this being bound is what goes against will being completely free.
By “free” will I would automatically assume; Will is free, only to its limited available choices.
I do not have concrete evidence but only through correlation of what seems reasonable and logical. We have Archetypes inside of us that never cease to exist but only may be effectively managed or the lessening of influence upon ego through becoming conscious of the unconscious. I personally believe these archetypes tie into other planets, sun, moon and solar system(astrology), I believe they may have energies, vibrations and frequency all on their own as everything does that effect us as conscious individuals based on time of birth and through further planetary movement when one is alive. This would be an unconscious physical force in which is restricting as well as the unconscious restrictions we already face to completely shape self, to shape self one must remember or learn first in what they wish to represent and it them, if this is not done then one lives their life as a collection of exterior idealogy without even realizing or understanding their ego has become indoctrinated by such.
It shows as easy as day that will is not completely free, so why bother saying “free will” at all. All one has is their heart and their will, do not let them be tainted.
