Answer: A Kabbalist must be a part of and participate fully in everything in which humanity participates. He is a natural part of this world and therefore needs to exist in the same system in which everyone is found.
A Kabbalist cannot climb to a mountain peak and live there as a hermit. He must live together with everyone, have a family, have children, and earn money for his livelihood, etc.
