Answer: We all exist in one spiritual vessel, in one desire. The Creator created one soul and it is impossible to selectively care for just one part of it, but only for the entire, full vessel. Nothing exists “partially” in spirituality.
If we are talking about bestowal, then we have to be concerned with becoming a candle for the Creator, which means correcting the full vessel. Since the Creator made one, single desire, bestowal can only awaken in all of it entirely. And as Baal HaSulam explains in the article “Mutual Guarantee,” we exist only for this sake.
Therefore, a person who does not care for the common vessel does not care for himself. We just have to open our eyes and see that this is the exact same thing. The world is an imprint of what we have inside; it only seems to exist on the outside.
Therefore, the aim isn’t for “me to care for the world,” but to open my eyes, to see the truth and understand that care for the world and care for yourself is the exact same care. We have to dispel this fog and clearly see that this is one soul!
Instead of “awakening care for the world” inside myself, I have to take care of myself—of why I don’t see that the whole world is my spiritual vessel, my soul.
From this it is clear that I cannot stop caring for the world under any circumstances because this is the main part of me. Everything I feel inside of me now is just my body, and this sensation called “the body” will die one day and will disappear from my consciousness. And only the care that I will acquire for my external “body” will become revealed to me as my soul and will remain with me forever. In it I will acquire my true, eternal life.
This is the inner revolution we have to go through. Essentially, this is the meaning of passing the Machsom (the boundary separating us from the upper world). When a person begins connecting and identifying himself with what is outside instead of the ego that he previously perceived as being himself, this is called passing the Machsom.
Baal HaSulam says that this requires only a psychological revolution. This blindness and deception holds the reason for all of the evil we feel now.
