A Kabbalist rejoices in the bad just as in the good. However, this does not mean he is a masochist because a Kabbalist does not attribute suffering to himself but only to egoism, which was created by the Creator. And he perceives egoism not as his own desire to enjoy but as a force coming from the Creator.
He looks at his animalistic body as a researcher. In the animalistic body the force of reception, egoism, is revealed, but a Kabbalist wants the force of bestowal to be revealed in him. He sees himself as a completely neutral researcher, not belonging to either reception or giving.
