comparison with a corresponding psychological state in human spiritual experience. In Hasidic philosophy, which has sought to internalise the experience of Jewish mysticism into daily inspiration (devekut), this inner life of the sefirot is explored, and the role they play in man's service of God in this world. Ein Sof The Ein Sof (lit: without end) is an important concept in Jewish Kabbalah. Generally translated as "infinity" and "endless", the Ein Sof represents the formless state of the universe before the self-materialization of God. In other words, the Ein Sof is God before he decided to become God as we now know him. The sefirot are divine emanations that come from the Ein Sof in a manner often described as a flame. The sefirot emanate from above to below. As the first Sefira is closest to Ein Sof, it is the least comprehensible to the human mind, while in turn the last is the best understood because it is closest to the material world that humanity dwells on. Ten sefirot Sefirot (, sfirot, singular sfira), literally means "counting, enumeration", but early Kabbalists presented a number of other etymological possibilities from the same Hebrew root including: sefer ("text" - ספר), sippur ("recounting a story" - סיפור), sappir ("sapphire" - ספיר, "brilliance", "luminary"), sfar ("boundary" - ספר), and sofer, or safra ("scribe" - ספרא, סופר). The term sefirah thus has complex connotations within Kabbalah. The original reference to the sefirot is found in the ancient Kabbalistic text of Sefer Yetzirah, "The Book of Formation", attributed to the first Jewish patriarch, Abraham. However, the names of the sefirot as given in later Kabbalah are not specified there, but rather are only identified by their attributes "forward", "backward", "right", "left", "down", "up", "light", "darkness", "good" and "evil". Further references to the sefirot, now with their later-accepted names, are elaborated on in the medieval Kabbalistic text of the Zohar, which is one of the core texts of Kabbalah. The sefirot are 10 emanations, or illuminations of God's infinite light as it manifests in creation. As revelations of the creator's will ( rɔṣon), the sefirot should not be understood as 10 different "gods", but rather as 10 different channels through which the one God reveals His will. In later Jewish literature, the 10 sefirot refer either to the 10 manifestations of God; the 10 powers or faculties of the soul; or the 10 structural forces of
