Rabash: “Angels” who go up and down the ladder are people who say that they were sent into this world to perform corrections, and that is why they are called angels. If they see that they are in a state of descent, darkness, they should “descend.” But first they were in an ascent, otherwise it is impossible to feel that one is in a state of descent.… So only as much as you aspire to do good will you see how much evil is in you.
It mainly relates to the work in the group. The more a person tries to do good in it, the faster he discovers that he is not able to and he has no chance to advance. To discover the real darkness, we must rise first. It’s just like it says: “The advantage of the Light is from the darkness.”
First you need to rise, to receive new attributes and discernments, and to be closer to bestowal in order to later see what is going on in you. Then you will always see greater darkness inside you.
Of course, the darkness wasn’t created now, you simply didn’t notice it before. By rising above it and being able to compare different attributes and values, you can now see that you were in the dark, in your egoistic desires.
This is why we should aspire only to the good and the evil will be revealed by itself. There are people who are looking for the evil, digging into it, and drowning in it. However, the real evil is revealed only by ascending and experiencing joy, by understanding how good it is that the evil has been revealed. Even when a person reveals the evil, he is happy. It is a sign that the evil is purposeful, that is revealed along the way, and that an ascent is constant.
But if a person falls and despairs, if he tortures himself, it is a sign that he isn’t on the right track yet. A person should advance by the left line too, and not only by the right line—by walking on two legs forward. But he shouldn’t sink into the left line, into a descent.
If a person receives support from the environment and the books, if he listens to the teacher, learns, and understands that he must only think about the positive advancement that is awaiting him ahead, and not about anything bad—only about the greatness of the Creator, then he saves time and advances constantly.
On the way upward there are dark and bright moments. And specifically where everything first seemed totally bright he now discovers the darkness, and more and more each time. This means that he discovers the left line in an ascent.
