Sacrifice, Korban (stemming from the Hebrew root to come closer), means that I sacrifice my ego in order to rise above it. If I do so in order to reach the attribute of bestowal, it helps me to advance. If it is the opposite and I do it in order to receive, it’s called paganism and so it is forbidden.
Question: Why do I behave that way if it’s forbidden?
Answer: You do so because you receive egoistic pleasure by it. A person can stumble and do something wrong on every level, since it has to be his freewill. To stumble means that one just stumbles but does not fall. This means that the fall is relative: I am thrown from the level I am on so that I will learn and rise even higher or so that I would fall as a result of my own doing. This is an intentional fall.
It says: “For a righteous man falleth seven times, and riseth up again” (Proverbs 24:16). When a person advances persistently, he is called a righteous. He will keep on falling and rising, falling and rising, since he is tripped on purpose so that he will learn to advance. If he prepares the fall in advance by himself, he cannot advance.
