I find that my compulsive philosophizing has generated a fairly complex schema to account for what I regard as the major facts of existence: the basic components of reality.
In a nutshell I am trying to explain Mormon cosmology here: I am trying to flesh-out the 'back story'.
Initially there is matter, laws of nature - including moral laws, there is God (the Father) (and perhaps a Heavenly Mother, I'm not sure: either God is the one entity without sex, or the duality and incompleteness of sex are universal facts, and the basis of all action and movement and purpose)
...and there are individual (but not personalized) essences of agency, which are differentiated by sex (i.e. male and female agents).
At this point in history, only God has agency and free will - plus many other great primordial powers and attributes.
That is the set-up. The assumptions. This is what JUST IS.
So we have an eternal pre-existence, eternal autonomy as pre-persons - but at that point we had no self-awareness, and no capacity for free will - no capacity to act.
God wanted to have children, he wanted to raise-up these children to become friends, eternal companions, allies in living...
Why? Either because he was alone and lonely; or because he was an incomplete half and eternally accompanied by a Heavenly Mother - such that the basic dynamic of the universe is to seek completeness in celestial marriage and the loving company of children, and therefore to raise these children to the same maturity as their parents.
When we became children of our Heavenly Father, our agency was additionally endowed with conscious self-awareness and the capacity to choose and act - free will.
At that point we became disembodied spirits (spirit children)
So we began as an eternally pre-existent, unaware, tiny and helpless, but autonomous, individual flame; to which (at some point in time) God added the divine flame with consciousness and the ability to act - and we embarked upon a spiritual existence.
When we chose to come to earth and live this mortal and incarnate life, we did this by earthly parents - so as we are born as mortals we have three sources of 'fire':
1. The individual eternal flame of agency. Unique to us.
(This is the reason why we have genuine and inviolable autonomy and are not merely aspects of God. This is why we are of the same kind as God - we share this basis. )
2. The divine flame - shared with God and with all God's children. This is the reason why all Men are brothers and sisters.
3. A family flame, blended from the individual flames of our earthly parents.
To this is added personal experience, as a consequence of our choices, the choices of others, and the 'physical' constraints of earthly life.
So we are compounded of these - we are unique individuals, and we are embedded in relationships as Sons and Daughters of God, Family members, and a product of our choices and chances including friendships and broader human society (maybe Churches).
Our purpose is theosis, to become like God: starting from our shared essence with God to build upon this and to progress through incremental stages of learning and experience; we are now in the midst of this process - being incarnate mortals with avast history behind us including pre-mortal spiritual existence - and an eternity before us of post-mortal first spiritual then resurrected existence.
And this process is foundationally relational, although we are indeed individuals and intriniscally different from every other individual - we are embedded in relationships: the relationships by virtue of sharing in the status of being God's children, and also additional between-human family relationships.
More than this, the very movement, purpose and direction of reality depends upon sexual differentiation - upon there being men and women neither of whom are complete humans: the only complete human is a man and woman united, eternally sealed, but this unity is internally structured: is of its nature both dyadic and dynamic.
Sexuality and its union in marriage, and its seeking fulfilment in children and families bound by love, is what makes the universe go.
