One should not dwell in the previous stage, but should immediately enter into the next level and accustom oneself to such a change of states. If we stop in a particular state, this is not good. All changes are for the good; the main thing is that there should be changes.
It is written, (Isaiah 2:3) “For out of Zion shall go forth the law,” meaning departing from the previous state, even the best. This is even if it’s a fall from a higher state, from joy to sorrow. This is not important, only that there should be as many changes as possible because they determine the rate of advancement.
We always advance, stepping with the left foot or with the right foot; that is how movement is made. Therefore the main thing is not to stand on one leg in the same spot, rather to move all the time: from the left line to the right, or from the right to the left. The main thing is to go out of the previous state and enter into a new level of connection.
The ascents and descents happen all the time. They say that the Seer of Lublin said to his student who was complaining about the constant ascents and descents that he passed through 400 ascents and descents in the morning. It’s not necessary to think that he counted them, he simply knew the number of levels that he had risen: that is, the level where he had been before and the level to which he had risen. And that is how he knew that they were 400. Additionally, 400 is a number that symbolizes completion.
The more internal changes happen within a person, the better. And it’s not necessary to analyze them as to whether they are good or bad. There are no bad changes! Baal HaSulam writes: “I am happy about the wickedness that is revealed”; you see, if they are revealed this says that it’s possible to correct them. Even though it’s bad for me, I am happy that I can correct this evil. Therefore it’s good that you are going through many ascents and descents.
And in addition, this helps the friends. Everyone goes through many inner changes, and through integration we convey these ascents and descents to one another. So it follows that everyone wins and advances quickly.
