The Creator, in a way, gives Baal HaSulam a higher power as a pledge: “As long as you keep the sword (that is, that which can be damaged with a sword, you will correct with the help of the same power), know that I am with you, in your soul, and my strength is with you.”
The sword is the power that cuts, chops. It can chop off heads, cut off unnecessary parts from you, and leave only healthy ones. Spiritual healing boils down to several processes.
The same is true in our world: medicinal treatment and surgical treatment.
In both treatments, there are two effects on humans. Either the unnecessary, harmful part is cut out or is destroyed chemically with the help of drugs. Or vice versa, either some part is sewn, bypasses are made, shunts put in the human body, or the functioning of the body is restored with the help of drugs.
In principle, there is only one approach. Both are called treatment. One by destructing, the other by restoring. Both are necessary.
Therefore, it cannot be said that the sword does harm when it chops off heads. It has to chop them off because they are egoistic heads.
But when a period of war passes, a period of recovery is needed. That is, people need to be given a different methodology, a different paradigm of life, and they must recover.
