Q: : I have heard that there are just 36 tzaddikim (righteous individuals) in the world. What about the rest of humanity?
A: There are 36 complete tzaddikim. However, there are many, many tzaddikim and good people, who, although they have not reached the lofty heights of the complete tzaddikim, are still considered righteous individuals. There is also the one tzaddik in every generation, who is likened to the Moses of that generation, and merits to receive the Shechinah every day. This tzaddik is the foundation of the world in his time. The simple Divine service of all of these tzaddikim, and of every person, brings G-d much Nachat Ruach (pleasure).
