Answer: Love is the connection of my desire with other desires. Since all of us come from one desire called Adam, the discovery of the upper world is summed up by the combination of separate, isolated desires that reject each other. So, to the degree of the union of these desires, we begin to perceive the upper world.
Comment: It is often very difficult for a person to define a feeling of love or hatred. As long as he is not in the upper world and is within the framework of our world, all the stereotypes, routines, and models of this world influence him.
Answer: Therefore, a person cannot go out to the upper world until he overcomes his rejection of other people.
