Aside from the many details, what is a key principle you have learned by studying the system of Worlds?

I have learned that I am able to ascend to the different levels of the worlds of BYA through my studies, enhanced by connection to teachers and friends. I am able to feel and receive the Light of the Creator, increasing at each world and each level within each world. But I cannot reach the point of the last correction in the world of Atzilut  until I am able to fully know and feel the completion of the assembly of souls within myself. I must adhere to the complete machine, all souls, before final adhesion with the Creator, in this life.

I am understanding that itś all about the balance of receiving to bestow; that this is how creation was formed. and that this is not relating to definite entities, but to forces, and therefore itś like  natural laws. I also understand that there is a definite system of how these forces are being transformed, in terms of their level of energy. And I understand that the shattering was part of these given conditions; so there is no moral thinking in it, itś just what it is.

To ascend to the next world I have to have a screen capable of reflecting back to the Creator that light.

I have learned how all the worlds interact with each other. How we are separated from these higher worlds and we must work hard to get back to the higher world by climbing that mountain. I can understand the story of Jacobs ladder as a result of understanding these worlds. How we are at the bottom pit and must seek the truth and get out of this illusion. I understand how these worlds relate to our body. How these worlds are similar to the human make up of our mental and physical body.

How the ladder was made from top down and now we have to climb it from below up

How one can ascend and correct oneself.
Am confused not sure.
