The Tzadikim Nistarim (Hebrew: צַדִיקִים נִסתָּרים, hidden righteous ones) or Lamed Vav Tzadikim (Hebrew: ל"ו צַדִיקִים, 36 righteous ones), often abbreviated to Lamed Vav(niks),[a] refers to 36 Righteous people, a notion rooted within the more mystical dimensions of Judaism. The singular form is Tzadik Nistar (Hebrew: צַדִיק נִסתָר).
The source is the Talmud itself, explained as follows:
As a mystical concept, the number 36 is even more intriguing. It is said that at all times there are 36 special people in the world, and that were it not for them, all of them, if even one of them was missing, the world would come to an end. The two Hebrew letters for 36 are the lamed, which is 30, and the vav, which is 6. Therefore, these 36 are referred to as the Lamed-Vav Tzadikim. This widely-held belief, this most unusual Jewish concept is based on a Talmudic statement to the effect that in every generation 36 righteous "greet the Shechinah," the Divine Presence (Tractate Sanhedrin 97b; Tractate Sukkah 45b).
Their purpose 
Mystical Hasidic Judaism as well as other segments of Judaism believe that there exist 36 righteous people whose role in life is to justify the purpose of humankind in the eyes of God. Jewish tradition holds that their identities are unknown to each other and that, if one of them comes to a realization of their true purpose then they may die and their role is immediately assumed by another person:
The Lamed-Vav Tzaddikim are also called the Nistarim ("concealed ones"). In our folk tales, they emerge from their self-imposed concealment and, by the mystic powers, which they possess, they succeed in averting the threatened disasters of a people persecuted by the enemies that surround them. They return to their anonymity as soon as their task is accomplished, 'concealing' themselves once again in a Jewish community wherein they are relatively unknown. The lamed-vavniks, scattered as they are throughout the Diaspora, have no acquaintance with one another. On very rare occasions, one of them is 'discovered' by accident, in which case the secret of their identity must not be disclosed. The lamed-vavniks do not themselves know that they are ones of the 36. In fact, tradition has it that should a person claim to be one of the 36, that is proof positive that they are certainly not one. Since the 36 are each exemplars of anavah, ("humility"), having such a virtue would preclude against one’s self-proclamation of being among the special righteous. The 36 are simply too humble to believe that they are one of the 36.
Lamedvavnik is the Yiddish term for one of the 36 humble righteous ones or Tzadikim mentioned in kabbalah or Jewish mysticism. According to this teaching, at any given time there are at least 36 holy persons in the world who are Tzadikim. These holy people are hidden; i.e., nobody knows who they are. According to some versions of the story, they themselves may not know who they are. For the sake of these 36 hidden saints, God preserves the world even if the rest of humanity has degenerated to the level of total barbarism. This is similar to the story of Sodom and Gomorrah in the Hebrew Bible, where God told Abraham that he would spare the city of Sodom if there was a quorum of at least 10 righteous men. Since nobody knows who the Lamedvavniks are, not even themselves, every Jew should act as if he or she might be one of them; i.e., lead a holy and humble life and pray for the sake of fellow human beings. It is also said that one of these 36 could potentially be the Jewish Messiah if the world is ready for them to reveal themselves. Otherwise, they live and die as an ordinary person. Whether the person knows they are the potential Messiah is debated.
The term lamedvavnik is derived from the Hebrew letters Lamed (L) and Vav (V), whose numerical value adds up to 36. The "nik" at the end is a Russian or Yiddish suffix indicating "a person who..." (As in "Beatnik"; in English, this would be something like calling them "The Thirty-Sixers".) The number 36 is twice 18. In gematria (a form of Jewish numerology), the number 18 stands for "life", because the Hebrew letters that spell chai, meaning "living", add up to 18. Because 36 = 2×18, it represents "two lives".
In some Hasidic stories, disciples consider their Rebbes and other religious figures to be among the Lamedvavniks. It is also possible for a Lamedvavnik to reveal themselves as such, although that rarely happens—a Lamedvavnik's status as an exemplar of humility would preclude it. More often, it is the disciples who speculate.
And the Lord said, If I find in Sodom fifty righteous within the city, then I will spare all the place for their sakes.
It is said, that the assumed founder of the Jewish Hassidic Movement, Israel Ben Eliezer, known as the Baal Shem Tov, studied with a secret society of Jewish mystics, the Nestarim or Nistarim, and he eventually became a revered rabbi.
