Seven Pillars to Judaism

Mezuzah:
Thus, a mezuzah has come to refer also to the parchment, or klaf, on which the verses of the Torah are inscribed (Deuteronomy 6:4-9, 11:13-21). Mezuzah refers as well to the case or container in which the parchment is enclosed. A mezuzah serves two functions: every time you enter or leave, the mezuzah reminds you that you have a covenant with God; second, the mezuzah serves as a symbol to everyone else that this particular dwelling is constituted as a Jewish household, operating by a special set of rules, rituals, and beliefs. (http://www.myjewishlearning.com/life/Life_Stages/Building_a_Jewish_Home/Home_and_Community/Mezuzah.shtml)

Tefillin:a set of small black leather boxes containing scrolls of parchment inscribed with verses from the Torah, which are worn by observant Jews during weekday morning prayers. (http://en.wikipedia.org/wiki/Tefillin)

 Shofar: a horn, traditionally that of a ram, used for Jewish religious purposes. Shofar-blowing is incorporated in synagogue services on Rosh Hashanah and Yom Kippur. Shofar come in a variety of sizes. /http://en.wikipedia.org/wiki/Shofar)

Hanukkah: an eight-day Jewish holiday commemorating the rededication of the Holy Temple (the Second Temple) in Jerusalem at the time of the Maccabean Revolt of the 2nd century BCE. Hanukkah is observed for eight nights and days, starting on the 25th day of Kislev according to the Hebrew calendar, which may occur at any time from late November to late December in the Gregorian calendar.

Kosher: The laws of “Kashrus” include a comprehensive legislation concerning permitted and forbidden foods. Among the numerous laws that form part of kashrut are the prohibitions on the consumption of unclean animals (such as pork, shellfish (both Mollusca and Crustacea) and most insects, with the exception of crickets and locusts), mixtures of meat and milk, and the commandment to slaughter mammals and birds according to a process known as shechita (http://en.wikipedia.org/wiki/Kashrut)

Tzedakah: In Judaism, tzedakah refers to the religious obligation to do what is right and just, which Judaism emphasises are important parts of living a spiritual life. Maimonides says that, while the second highest form of tzedakah is to anonymously give donations to unknown recipients, the highest form is to give a gift, loan, or partnership that will result in the recipient supporting himself instead of living upon others. Unlike philanthropy or charity, which are completely voluntary, tzedakah is seen as a religious obligation, which must be performed regardless of financial standing, and must even be performed by poor people.

Sabbath: weekly day of rest or time of worship observed in Abrahamic religions and other practices. (http://en.wikipedia.org/wiki/Sabbath)
