Tzadik ( “righteous one;” pl. tzadikim) is a title which is generally given to those who are considered to be righteous such as a spiritual master or rebbe. The root of the word tzadik, is tzedek , which means justice or righteousness. This term thus refers to one who acts righteously.
In classic Jewish thought, the true title of tzadik can only be applied to one who not only never sins, but also has eradicated any inclination to do so.
The Talmud says that at least 36 Tzadikim Nistarim — anonymous tzadikim — are living among us at all times; they are anonymous, and it is for their sake alone that the world is not destroyed. The Talmud and the Kabbalah offer various ideas about the nature and role of these 36 tzadikim.
