Asceticism is a lifestyle characterized by abstinence from sensual pleasures, often for the purpose of pursuing spiritual goals. Asceticism has not been a dominant theme within Judaism, but minor-to-significant ascetic traditions have been a part of Jewish spirituality.[1]
Many Jewish sources describe the physical world as essentially good; the human body as a servant of the spirit, and therefore not corrupt; the human being as possessing dignity as one made in the image of God; and physical pleasures as God-given and therefore to be enjoyed with gratitude toward the divine giver. One who refuses to partake of the material world was even described as a sinner by Samuel of Nehardea in tractate Taanit (Taanit 11a).
At the same time, other sources recommend and even require Jews to avoid intemperate and extravagant behavior, which is seen as leading to bad character traits and sometimes to outright sin. Thus Jews were recommended to moderate their eating and drinking and sexual behavior; to "sanctify" their material consumption by intending its ultimate purpose to be enabling service of God rather than selfish pleasure; and where appropriate to make extra "fences" around the law by avoiding specific activities that seem likely to lead to sin. Overall, Judaism recommends moderation rather than total abstinence, a balance perhaps best represented by Maimonides' "golden middle way" between sensual luxury and tortured self-deprivation.
In addition, many sources suggest that members of the spiritual elite would be best served by a greater level of asceticism than the masses, including practices such as fasting and sexual abstinence, in order to enable them to focus on Torah study or else mystical contemplation. While such behavior was generally the choice of pious individuals, in a few cases it became the focus of widespread communal movements, particularly the Ashkenazi Hasidim and Lurianic Kabbalah.
