Well, the answer is found, because of which hatred for him arose. Now you need to try to take the place of the hated person. Mentally switch roles and analyze your and his behavior at the moment when hatred arose. Would the same thing happen or not? Perhaps the hated person does not even suspect such an attitude towards him. Indeed, very often it is to those to whom hatred arises that special attention is paid. The hater is especially attentive and courteous, and the hater considers it sympathy. If so, the easiest option would be to talk. Discuss what does not suit the person, what he should not say and do. Most likely, this will have its effect - and then the whole problem will be eliminated.

Forgive the person you hate. It would seem that it could be easier than to forgive a person who does or has done something unpleasant.

And then it will be possible to let go of hatred, without focusing on the actions of man.
