Answer: We generally understand this quotation as an obligation to injure someone else because he apparently injured me. On the contrary, I should be grateful that he is teaching me about a characteristic that is harming me. If I were corrected, nothing could have an influence on me; I would be absolutely impervious to all kinds of “arrows.” It would be impossible to irritate me and I would not be indignant or insulted because in a perfected state there would be nothing in me that others could hold onto.
And so, if someone were to say something insulting to me or I were to see something that harms me or is personally directed at me, it only indicates my uncorrected state. If I correct myself, in this way I correct the world around me and I stop seeing negative characteristics in it.
Instead of our terrible world, I suddenly begin to see myself in the spiritual world, in Olam Ein Sof (world of Infinity). It only depends on the correction of my personal characteristics, not on the correction of others, because the world is my opposite side, which shows me what I have not yet corrected inside.
Question: Does this mean that I don’t have to respond with the same “measure for measure”?
Answer: I have no answer for that. You should immediately turn to yourself. If you see, hear, or feel something negative from someone, it is because there are uncorrected characteristics in you. You must think and acknowledge that they are showing you precisely what you must correct within yourself.
