Answer: A person wants to sacrifice himself; he yearns unknowingly and without understanding that the spiritual action he performs is beyond his powers.
But this action is necessary so he can see the limits of his powers, so that his yearning forward will die, which means shatter; it disappears due to the unprepared form he made. But later he will be able to perform it as a result of many small actions.
Try to jump three meters high! The sons of Aaron wanted to take this level of in order to bestow for the sake of the Creator, for the sake of the whole nation, but it was beyond human powers, beyond the level they were on. Therefore, eventually the attribute of judgment was revealed, the rigidity, fire that can be both good and bad. In this case it swallowed them.
Question: But they did it with the right intention.
Answer: Their intentions were not justified. How can you go on such a mission if you don’t have the Creator’s clear support? All your attributes, all your actions of bestowal, stem only from the power you receive from Above.
You are nothing but a small egoist. Some new egoistic attributes are revealed in you, while you have to receive altruistic attributes, to connect them and to reveal the middle line on which you should work. This is called sanctifying a property, the attribute of bestowal, when you attract your ego, correct it by the altruistic attribute of the Light, and keep on advancing.
But if you don’t do that you have no right to use only the left line, no way!!
This is especially true on the level of the sons, since this is a small level. But Nadav and Avihu took the great egoistic potential that was revealed, which wasn’t prepared for them at all. It is like a youth who takes upon himself what even an adult cannot do since the adult understands that it isn’t in his power to do, while the youth thinks that he will be able to perform the mission he is given. But things aren’t that simple.
A the saying goes: “If youth knew; if old age could.” Therefore, old people realize that they cannot do something and don’t do it, while the foolish youth think that they can handle a task and gets so fired up that he gets burnt.
