Baal HaSulam, Shamati #70, “With a Mighty Hand and with Fury Poured Out”: …those who want to enter God’s work in order to truly cleave unto Him and enter the King’s Palace, not every one is admitted. Rather, one is tested—if he has no other desires but only a desire for Dvekut (adhesion), he is admitted.
And how is one tested if he has only one desire? One is given obstructions. This means that he is sent alien thoughts and alien messengers to obstruct him so he would leave this path and follow the path of the populace.
Baal HaSulam writes that everything in nature is attained in collision. Life is a struggle, not with someone or something, but rather with yourself. If a person understands this correctly, then everything is fine.
It all depends on how to attune to this to understand that two forces are governing in the world: reception and bestowal. The force of reception is our great egoism and the force of bestowal does not exist in us. We must develop it gradually. It is quite complicated.
In order to do so, we must somehow interact in the group, trying to come closer to each other. We do not want this. It is exactly at this point, when I feel that I do not want to, but I forcibly push myself to connect with the friends, that I must turn to the Creator and ask Him to give me an opportunity to want this. If I do not run away from the struggle, but I catch myself on this, I can then reach balance in the middle line.
Question: What are alien thoughts?
Answer: These are any thoughts that are not directed to adhesion with the Creator, to equivalence with Him, and to the quality of bestowal.
