Chasidut zu Mischlej 19:3

And if you begin with them from your childhood, you will be able to improve yourself in many details of divine service and self-improvement to the point that they become second nature for you, and will not have to remind yourself about them each time. For example, you can reach the level that when you walk in the street, you will not have to close your eyes in order for you not to see evil. Rather, you will automatically not see it. You will not have to avert your eyes from falsehood, as the eyes themselves will not see falsehood. Do not imagine that we are making a mistake to think that you will quickly sanctify yourselves so much that even if your eyes look at something forbidden, you will not see it - like King David requested. You should know, dear son, that it is not us that are mistaken but the people of the world that are mistaken - to think of this world that God created as a type of storehouse of bad desires, thoughts and inclinations; and that whoever wants to serve God is forced to leave and distance himself from the whole world. And because of this [self-defeating perspective], they distance themselves from divine service and holiness, and become mired in the stupidities of the world. They are similar to someone who sees a man drown in the river, and so decides and says that water is the essence of evil in the world and that it was created just to kill. And how foolish is such a man! Is it possible to exist without water? Is it because this one crazy person did not know how to use water properly and - instead of using it to give life to plants, animals and people - killed himself with it, that water is evil? Likewise is it with the whole world. It is a world that God created. So even the depths of the world - in all of their bends and all of their twists - have paths, furrows and caves that lead to its Creator, to its Master, to the Master of the world. And all the shortcoming are only in man, who does not use the things in the world for the good, but rather for the bad. The verse proclaims [this] and says (Proverbs 19:3), "A man’s folly distorts his way, and his heart rages against the Lord." Is it not that you have paths that lead you to God, and it is only you that distorts them? So why do you continue to get enraged and speak perversion - that God, God forbid, created a world of physicality in which it is impossible to serve its Creator?
