Torah, “Leviticus” Kedoshim 19:17: Do not harbor hatred in your heart towards your brother. The Torah describes the immense hatred that exists between brothers. They say that there is a thin line between love and hate.
The blood ties don’t operate on the next level of connection, the realization for the sake of the ascent, and are expressed as hatred, competition, and confrontation, while a person views his own brother as a huge interference.
There is a very fine line between “you and I are brothers in the goal of the ascent” and “we are just brothers.” If we are just brothers, then we’re competitors.
We have one father, and I want to be his sole heir. I don’t want to depend on someone else and owe anything to anybody. I always owe to a brother, since I depend on him due to the blood ties. If he does something that is either good or bad, somehow the light shines good or bad upon me.
A brother is a very big obstacle. He and I are equal before the whole world, but I don’t want to deal with anyone being equal to me. He expresses something that I can’t by his actions, and by doing so, he uncovers me since we are from the same level and from one father and mother.
So if I want to hide something, do something one way and not the other, then he will do it in his own style, deciding his own way, and possibly complete me, or vice versa, by being ahead of me. I depend on him and his actions always shine a good or a bad light upon me.
The concept of brothers is essentially non-existent in our world. In fact, this is a very delicate connection.
