And Korah assembled all the congregation against them unto the door of the tent of meeting; and the glory of the LORD appeared unto all the congregation.
“And the glory of the Lord appeared unto all the congregation” refers to a spiritual ascent. When a person raises MAN (prayer) and wants to be fully connected with the attribute of love and bestowal only, it is called offering incense, which symbolizes the ascent of our desires upward.
The attributes of Korach and Moses and the 250 desires that accompany them ascend upward in MAN to the next level.
This next level is the Creator with respect to the previous level of the created being. In it it is revealed whether Moses or Korach was right. The choice is made by the help of the Upper Light, the upper attribute that is revealed on that level.
Moses, Korach, and all the 250 people of his congregation totally nullify themselves, which means that all these attributes are incorporated in the next level where the solution to the problem—which of these two attributes is closer to the current level is found—and how one can ascend to it.
Then the attribute of Din (judgment) is revealed, which kills Korach and his congregation. This is their correction! All the other attributes quietly disperse to their places and then continue to advance.
