Answer: It is really that way. Baal HaSulam wrote that man is frightened since it seems to him that he disappears from this world and leaves his family and his friends. This is the difficulty in the work of the Creator.
That is exactly the feeling that we must experience, and we must receive the point of detachment from self-worry with joy. It is especially from these points that we build our identity. Each man’s identity is composed from those same points of detachment. This is a physiological example of total devotion.
