The Torah, “Leviticus” (Shemini), 10:6-10:7: And Moses said to Aaron and to Eleazar and to Ithamar, his sons,”Do not leave your heads unshorn, and do not render your garments, so that you shall not die, and lest He be angry with the entire community, but your brothers, the entire house of Israel, shall bewail the conflagration that the Lord has burned.
And do not go out of the entrance of the tent of meeting, lest you die, because the Lord’s anointing oil is upon you.” And they did according to Moses’ order.
Question: How can we explain that they are not allowed to mourn?
Answer: This does not refer to people who behaved recklessly and were somehow burned but about souls. When we speak about spiritual corrections allegorically, it is sometimes expressed in a very special way.
There is a state in which you should mourn since the mourning is actually a correction. This doesn’t mean that you should sit and cry since there is no one to cry about here. It isn’t about the corporeal concept of mourning, which is observed on the corporeal level.
The seven days of mourning mean that during these seven days (seven Sefirot): Hesed, Gevura, Tifferet, Netzach, Hod, Yesod, Malchut, you gradually realize and perceive the full depth of your fall and the reasons for it.
Therefore after the seven days, you understand the meaning of your fall; you are ready to start the correction, the rebirth of the desire that died against your will, just as it was against their will that Nadav and Avihu lit the Holy fire, burned incense, entered the Holy of Holies, and tried to perform an action.
In order to correct something, you must first descend to the darkest depth of your desire and fully perceive the extent of the shattering; the repulsion felt among all the parts of the general soul. Only after you attain the shattering are you able to turn to the Creator from the depth of this state, having understood that it wasn’t you who did it, but the Creator.
It is actually from the full depth of the descent when you feel that this is the end that you begin to feel that this state is given to you on purpose so that you will acquire contact with the Creator because the shattering and the correction are not important. What’s important is that you acquire contact with Him above all these states.
