The Kabballah Tree of Life is basically a skilltree, similar to the chakra system. each of the circles references a "skill" or concept to be unlocked which the each influence another based on how a point is skilled. To unlock the next you must unlock the one before starting at the bottom. You can take the left or the right path or at the optimum a balanced one. left and right are opposed to another, they are represented by the 2 pillars in freemasonry, Boaz and Jachin and symbolize the duality of this world. good and evil, light and dark, strength and beauty, and supposedly you can achive godhood/God by reaching the top. Now this is very important: You cant.
Kabballist or gnostics usually try to push moral relativity. For example where gnostics say "All is one, one is all, thus God is also evil and i can find him through that just as i can find him through good" or through "God is merely a ruleset, the laws of nature and has no will, thus there is no absolute authority there saying what is good and evil and thus my definition is as good as the next one". Similary Kabbalists try to argue you need to do both, good and evil to find the middle path that leads right to God.
Lets look what the serpent baited Eve with
>5“For God knows that in the day you eat of it, your eyes will be opened and you will be like God, knowing good and evil.”
>you will be like God
Godhood through works/knowledge, and look where this brought us to. The only way Gnosis/knowledge leads to Godhood/salvation is by realizing that there is one true God and that only he can save you, and that this is Jesus Christ. All roads lead to rome and as such all logic leads to God.
