Why incarnation

What is the reason for incarnation? Why does fundamental consciousness incarnate? What does state of non-incarnation mean (Being non-attached all the time)? After having achieved the state of non-incarnation, is there any possibility of incarnating again (say for benefit of others or anything else)? Does consciousness 'choose' to incarnate in a particular set of circumstances (essentially to gain some experience)? Where does the need for such experience arise?
Does consciousness have desires in itself?

Consciousness does not have desires in itself per say. But FC is an array of experieces plus more. FC in non-manifest form stores these experiences in an array (just like memory locations in a computer). In each array, there are some basic experiences (which form the basic reason for incarnation. Whatever is stored here can't be altered and are a part of 'what is' for a particular incarnation. These include attributes like birth time, duration and death). There are 'derived' experiences also. These derived or serrogate experiences support the cause of manifestion. These can be altered if one is aware enough.
For the purpose of animating this set of experiences, FC needs to 'limit' its 'all knowing' status. Otherwise, it will not be able to observe/experiece that particular experience in totality. It makes use of soul (mind principle) which encapsulates that particular experience (just like in computer programming we declare classes to carry on a specified set of tasks. Each class further has functions which actually perform that task, but within the purview of that class boundary). Thus, soul is a part of FC. FC knows all about the soul, but the soul knows only what FC allows it to know. This soul thus stores information and carries on tasks that are 'what is' for a particular incarnation. When all these tasks have been performed, the set of derived experiences have a 'changed' status because of any new experiences in the incarnation. Now, further incarnations if any, for a particular soul depend upon these derived experiences. The incarnations for the soul in question last as long as the derived experiences last. When the derived experiences become minimal, then the density of soul also lessens and it becomes easier for it to merge back into FC.
Between the incarnations, a soul may rest and in a 'non incarnated state' and wait for its 'possiblity' or chance to get animated, which depends on the overall experiences that FC has to execute.
Regarding self realized people: Their set of derived experiences are less and so the soul stands a strong chance of merger/dissolution back into FC. Even though the soul still has to transcend itself and release all the experiences before final merger, still it is less dense and if the manifested soul lives in 'what is', s/he is able to minimize its manifestations.
Regarding other people (who live purely for themselves): Their derived experiences keep accumulating because of the added 'desires' and their 'attachments' to these desires. They act for the purpose of fulfilling the ever increasing desires and drift away from the initial small set of 'what is' and therefore, have to take birth again and again for the derived set.

Question:
FC is a set of experiences plus more. What is this 'plus more'? What else does FC comprise?

What is the role of force in the process of creation? If once a soul has been freed or does not hold any more experiences, can it then again incarnate or can it then be used for the purpose of creation?

Clue:FC is a set of experiences plus more. So, the dynamic part comprises the experiences. But there is a static part also that does not go any manifestation and thus does not change. What is this static part (The 'observer' status if fine, but what causes fc to undergo experiences to have 'observer' status?

What is more important factor in the process of incarnation - the soul or the experience (we always get attached to 'me' or the soul aspect and forget completely the fact that we are in other words, an experience. Soul is a vessel or a mode of transport for that set of experience)?
