All choices are result of predetermined pattern of variables governing every interaction of everything- true

Can all of these variables successfully be mapped, interpreted and predicted properly? The moment they have, haven't your thought processes then become another intricate variable? What dictates the constance of this pattern though? who is to say it is not in flux?

but yes, in relation to the environment, we are merely a complication of underlying elements, and thus can produce no other state of being than these factors will construct. But isn't this a rather souless approach to the lemma? What of consciousness? perception? sensation? Why presume it is a phantasmal play of dancing matter? What if a property of matter were to hold the precursors to consciousness itself?

Truly our only freedom is our conscious perception; but our perception is slave to environment. Is the illusion of choice still a freedom then? So ignorance would be the only freedom? As a religious person might say, "is this why god made us? to give us a freedom he can never know?"

What relevence does this have on the mindset? realizing this flow does not help you what-so-ever, because hypothetically even this recognition is a composition of situation in its own. But what if the only things that could be expressed in our level of reality must be through fabrics of that level. Like trying to express a meadow by using a painting. The image is already predetermined, but it is only representative of a deeper anomoly. As with the workings of the conscious mind, it may be only representative of a deeper entity, only recognized and expressed by screening through consciousness. Is it fair to say the ineffable depths of the unconscious mind sre governed by a constance, an direct environmentally interactive pattern? What if it were related to a chaos of sorts? Is it fair to say that every choice is predetermined then? besides.. to be predetermined (relative to absolutely everything, abolutely everything is predetermined), for it to be relevent to us, it must be predeterminable, clearly absolutely everything is undeterminable. As far as we are unsure of what is, we are unsure of what will be. It is in the perception of the individual to see choice or not, but we experience it regardless. Choice exists because relative to the perception it is present - relative to the absolute whole, it does not.

-----Relating to the question------

Hypothetically, destiny can be interpreted as being based on the more constant locked variables, while 'things left up for choice' are the more intricately developed acts (more difficult to predict and foresee; based on a higher density of variables).

The level of no-choice is the one where you let someone else define you. The level of choice is the one where you manage to elude pigeonholing.
