If we don’t receive the desire to bestow from the environment, we will not be able to reveal the spiritual world through our own efforts. Indeed, spiritual pleasure is infinitely greater than its corporeal counterpart. Even the smallest pleasure which we receive upon ascending to the first spiritual degree out of 125 is billions of times greater than all the pleasures of our world combined.
The “Big Bang” is the result of a tiny spark of Upper Light that infiltrated our world and caused our whole universe. And it was merely a tiny spark! Meanwhile, now we are primed to reveal the entire Light of NRNHY to its full measure. It follows that for this we will need unlimited vessels of reception.
Therefore, we cannot receive all this Light; otherwise, we would simply explode. This is why each person needs to build external Kelim (vessels) outside of himself. Only through connection, a mutual inclusion into one another, are we capable of achieving great external desires.
Even now we are all swimming in the Upper Light; we are just unable to feel it. There is no place inside of us that can be filled because we only have a tiny spark. In Baal HaSulam’s Letter No. 8 (Fruit of Wisdom, Letters), he describes the Light that is revealed in us:
“At the hour of attainment one feels the Upper Light which is revealed and based on all the reverse transformations. And it seems to a person, at the hour of attaining perfection, that all the suffering he had gone through was valuable because it allowed him to appreciate the sweetness and flavor of the Light, of uniting with the Creator. And all of his organs and tendons shall say and bear witness that anyone among the living in the world would gladly agree to chop off his hands and feet seven times a day, if only he could attain the flavor of adhesion for but a brief moment in his life.”
In other words, we need to understand that spiritual revelation is something infinitely stupendous, and we need to prepare our empty desires (Kelim) for it. A great inner work awaits us, and yet it is incredibly easy only if we do it together with love. This union determines everything!
If I unite with others and feel that I exist together with them in one Kli, in one desire, then the Light becomes revealed inside. It is written that “love thy neighbor is the main rule of the Torah (Light)” because love is a vessel for the Light.
