“And the LORD spoke unto Moses, saying: ‘Thou shalt also make a laver of brass, and the base thereof of brass, whereat to wash; and thou shalt put it between the tent of meeting and the altar, and thou shalt put water therein. And Aaron and his sons shall wash their hands and their feet thereat; when they go into the tent of meeting, they shall wash with water, that they die not; or when they come near to the altar to minister, to cause an offering made by fire to smoke unto the LORD….’” (Exodus 30:17-20)
In spiritual work a person must purify himself in all of his desires.
This speaks about the spiritual structure of our desires. The desires, like our bodies, are composed of a head and a body.
The main thing is our hands and feet, what we take and towards what we are going. Therefore it is necessary to wash them, for they constitute an instrument for our advancement, of our mutual cooperation with each other.
And the body itself is only the Sefira of Tifferet, which is passive relative to the hands and feet. For where your feet carry you and what you take in your hands is the responsibility of the head. But previously the head must take stock, and only after this is it possible to wash the hands and the feet, meaning, to purify the desires from an egoistic intention.
“They shall wash with water, that they die not” symbolizes that after purification of the desires, the person is no longer detached from the Upper Light; he doesn’t receive for his own sake, because this is spiritual death.
