Each person sees in others what he has learned about himself through spiritual experience, therefore a person's attitude towards his friend is a true indicator of the degree of self-knowledge he has achieved.
He who has known for himself, on the one hand, what depth, what power can reach the suffering of the human spirit, separated from the light of true existence, and on the other hand, what a person is when he is in God, he knows that every person is an immeasurably eternal value, greater than the rest of the world; He knows the dignity of man, knows that each "one of these little ones" is precious before God (Matthew 25:40), and therefore he will never even think about murder, will not allow himself to harm his friend or at least hurt him.
