Question: From the point of view of Kabbalah, why does a person suffer and what for?
Answer: A person suffers because he does not want to reveal the upper world he exists in but does not feel.
He suffers in order to develop his own desires in himself, because according to these desires, the capacity for its revelation will be disclosed. Therefore, we have no other possibilities to reveal the upper world without effort.
And for each attainment, it is clear what sort of effort you must make. At the same time, our ego will resist and force everyone to give a certain amount of effort. Without this, we will be unable to determine the size of the revealed picture, its depth, and all the colors and properties that determine this state.
