Dear Iamede,
I can perhaps help with your confusion because I asked same questions. They were answered by Kabbalah (I am still threading through it as in the place we are, we can never answer all questions ...and things are supposed to be like that for specific reasons).
Anyway to put it as simple as I can I will start with the story of creation.
In the beginning there was Cause. God.
The Source.
The only reality was infinite nonphysical energy that expanded endlessly.
Kabbalah calls this endless expanse Light. Every form of possible pleasure was included in this Light. Everything a person could conceive of, long for, crave or desire was included in this Light of happiness (from chocolate, sex, to bliss, serenity and so on).
This was the plane of the Creator. No time. No space....
The Creator then created all souls of humanity - one entity at that point - for one great purpose: to bestow this infinite Light of happiness upon us.
At that we were/are indeed part of the Creator, and Kabbalah gives an example to make this idea easier of that of water and ice. Imagine the Creator being water and Us a cup made of ice. Same stuff, same material ...just different state.
The Light was handed to us freely. The water was being poured into the cup.
At this point we can call the Creator the Bestower and we the Bestowed.
The Bestower created the Bestowed (us) simply deep out of this desire to share, to give, to impart all possible joy and happiness - the Light was handed to us freely. As being the Creator he needed for nothing as already having everything possible and imaginable, endless infinite all.
The primary property of the Creator (Bestower) was that of giving - sharing, and only for the sake of giving wanting absolutely nothing in return.
The primary property of the Bestowed (us) was that of receiving.
However as the Creator poured his Light into the cup ...some of the Light property was also imparted into the cup. Very much like you would pour hot water into an ordinary cup, the cup will get filled and get hot at the same time.
This property was that of the Creator's - that of giving.
It grew stronger (the cup was being filled with all that joy...) also the 'need' to Bestow until a point come when the Bestowed (the cup.... us) said: "Enough, I can't take all this beneficence anymore ..it feels like a handout, charity and it doesn't give me the dignity to be able to receive anymore if I am not given the opportunity to earn what I receive."
At that moment ..when the Bestowed said "STOP"- the Creator immediately retracted its Light and the cup shattered in the thousands of pieces which are the souls of humanity ..the physical Universe was created for these souls simply for the purpose of given an opportunity to earn the Light.
Thus duality come in place (and with it the 'choice' and 'free will'). The choice being actually only one: choosing to be 'like' the Creator or not. Choosing Light or darkness.
(darkness = being reactive and Light = being pro-active)
i.e. every time we are faced with a situation we have the freedom to chose Light ... responding to that as the Creator would do with love, understanding, tolerance, no matter how bad it is or how much it upsets or angers us ... or Darkness, the workings of selfishness, or Ego, falling into anger, envy, jealousy etc..
So us being here it was not a punishment... it was OUR choice. It was in us that we had such a high integrity that we were ready to endure the limitations of this physical life in order to be able to feel that we earned the Light of the Creator.
So, in the light of this story... you will see that the actual "work" is something that is no work at all IF we understand who we are, why we are here, and what our mission here is.
Life is a game and Universe is our playfield. Getting to the higher levels is simple, no work at all....as one wants and desires... it accumulates the knowledge to do it... the game has to have a bit of challenge in it else it will not have the difficulty required for us in order to FEEL that we earned it.
... then comes the power and strength to not fall for life simple physical pleasures at the expense of giving up our property of being creators... when that happens game is over and we are free to receive endless joy without guilt...
You can also look at it as a game ...we tell to the creator: "You hide the Light and we will seek."
Becoming God...
When we work at finding the Light we get a sense of accomplishment - we become responsible for our own happiness. We feel like God, like the Cause ..and nothing feels better than God as we receive endless happiness ... the package of this game.
I know this is a very brief account, things are a tad more complicated ...depending on or at which curtain of Darkness we are.
....however all spirituality made more sense to me after learning what I just told you. In all honesty I don't think there's an end to learning ...as there's no end to creation. When you think about it ...every time something gets created...something else comes up for learning.
The solace stands in getting your basics right. Then you can build upon that to whatever level you like to reach.
Good luck in finding your true path.
