The 613 Mitzvot (commandments) and the building of the Tabernacle signify the correction of the 613 desires in man. In order to construct the correct, reformed connection with the others, we must connect with them through 613 channels, similar to the vessels that connect all the organs in our body.
We need to correct these desires by having changed their egoistic intention to use others for self-gratification to the desire to bestow. Thereby, we will achieve a state where we will be interconnected by a global, integral connection as it exists in Nature and as our current world demands us to do.
Imagine that from each person, 613 desires expand like tentacles, stretching toward all the others. All of the desires intertwine and create a binding grid between us. In addition, each desire contains five levels of coarseness: 0, 1, 2, 3, and 4. All of this interweaves and tangles into one big, thick layer permeated by an enormous amount of the various types of ties.
This collective desire consisting of all our desires is regarded as Shechina (Divinity), the Tabernacle (“Mishkan” or dwelling place), the Temple, the receptacle, our integral vessel of bestowal, Knesset Israel (Assembly of desires for the Creator).
People who strive to go “straight to the Creator” (Yashar El) and desire to reveal Him bring all their desires together (Knesset or assembly) and build the collective desire where the Creator is revealed. This is the work to construct the Temple, the “house” of the vessel which you have built from your desires so that Divinity would unfold in it, meaning the spiritual property of love and bestowal, or the Creator.
In addition, you receive what initially had been prepared for you and all of us: the Light that fills this collective desire. So, it is regarded as the deposit, a guarantee (Pkudin, deposits, from the word Pikadon, recommendations, commandments, Mitzvot). You sacrifice (Makriv) your desire by nullifying your egoism and, thereby, bring yourself closer (Mekarev) to the Creator’s revelation.
