AtzmusAtzmus/atzmut ( from the Hebrew etzem) is the descriptive term referred to in Kabbalah, and explored in Hasidic thought, for the divine essence. Classical Kabbalah predominantly refers to the Godhead in Judaism with its designated term "Ein Sof" ("No end"-Infinite). Reference to atzmus is usually restricted in Kabbalistic theory to discussion whether "Ein Sof" represents the ultimate divine being in itself, or to God as first cause of creation.
Four WorldsThe Four Worlds (עולמות ʿOlamot, singular: ʿOlam עולם), sometimes counted with a prior stage to make Five Worlds, are the comprehensive categories of spiritual realms in Kabbalah in the descending chain of Existence. The concept of "Worlds" denotes the emanation of creative lifeforce from the Ein Sof Divine Infinite, through progressive, innumerable tzimtzumim (concealments/veilings/condensations). As particular sefirot dominate in each realm, so the primordial fifth World, Adam Kadmon, is often excluded for its transcendence, and the four subsequent Worlds are usually referred to.
Jewish meditationJewish meditation includes practices of settling the mind, introspection, visualization, emotional insight, contemplation of divine names, or concentration on philosophical, ethical or mystical ideas. Meditation may accompany unstructured, personal Jewish prayer, may be part of structured Jewish services, or may be separate from prayer practices. Jewish mystics have viewed meditation as leading to devekut (cleaving to God). Hebrew terms for meditation include hitbodedut (or hisbodedus, literally "self-seclusion") or hitbonenut/hisbonenus ("contemplation").
TzimtzumThe tzimtzum or tsimtsum (Hebrew: צמצום ṣimṣum "contraction/constriction/condensation") is a term used in the Lurianic Kabbalah to explain Isaac Luria's doctrine that God began the process of creation by "contracting" his Ohr Ein Sof (infinite light) in order to allow for a "conceptual space" in which finite and seemingly independent realms could exist. This primordial initial contraction, forming a ḥalal hapanuy "vacant space" () into which new creative light could beam, is denoted by general reference to the tzimtzum.
Jewish mysticismAcademic study of Jewish mysticism, especially since Gershom Scholem's Major Trends in Jewish Mysticism (1941), draws distinctions between different forms of mysticism which were practiced in different eras of Jewish history. Of these, Kabbalah, which emerged in 12th-century Europe, is the most well known, but it is not the only typological form, nor was it the first form which emerged. Among the previous forms were Merkabah mysticism (c. 100 BCE – 1000 CE), and Ashkenazi Hasidim (early 13th century) around the time of the emergence of Kabbalah.
SefirotSefirot (sfɪˈroʊt,_ˈsfɪroʊt; סְפִירוֹת, Tiberian: ), meaning emanations, are the 10 attributes/emanations in Kabbalah, through which Ein Sof (The Infinite) reveals itself and continuously creates both the physical realm and the chain of higher metaphysical realms (Seder hishtalshelus). The term is alternatively transliterated into English as sephirot/sephiroth, singular sefirah/sephirah, etc. Alternative configurations of the sefirot are interpreted by various schools in the historical evolution of Kabbalah, with each articulating differing spiritual aspects.
Hasidic philosophyHasidic philosophy or Hasidism (חסידות), alternatively transliterated as Hasidut or Chassidus, consists of the teachings of the Hasidic movement, which are the teachings of the Hasidic rebbes, often in the form of commentary on the Torah (the Five books of Moses) and Kabbalah (Jewish mysticism). Hasidism deals with a range of spiritual concepts such as God, the soul, and the Torah, dealing with esoteric matters but often making them understandable, applicable and finding practical expressions.
DevekutDevekut, debekuth, deveikuth or deveikus (Heb. דבקות; Mod. Heb. "dedication", traditionally "clinging on" to God) is a Jewish concept referring to closeness to God. It may refer to a deep, trance-like meditative state attained during Jewish prayer, Torah study, or when performing the 613 mitzvot (the "commandments"). It is particularly associated with the Jewish mystical tradition. דבק, or deveq, the modern Hebrew word for glue, literally means 'to cling'. It is sometimes referred to as devequt, "dvequt" or devequs.
GilgulGilgul (also Gilgul neshamot or Gilgulei HaNeshamot; Heb. , Plural: Gilgulim) is a concept of reincarnation or "transmigration of souls" in Kabbalistic esoteric mysticism. In Hebrew, the word gilgul means "cycle" or "wheel" and neshamot is the plural for "souls." Souls are seen to cycle through lives or incarnations, being attached to different human bodies over time. Which body they associate with depends on their particular task in the physical world, spiritual levels of the bodies of predecessors and so on.
TzadikTzadik (צַדִּיק ṣaddīq tsaˈdik, "righteous [one]"; also zadik or sadiq; pl. tzadikim tsadiˈkim ṣadīqīm) is a title in Judaism given to people considered righteous, such as biblical figures and later spiritual masters. The root of the word ṣadiq, is ṣ-d-q ( tsedek), which means "justice" or "righteousness". When applied to a righteous woman, the term is inflected as tzadika/tzaddikot. Tzadik is also the root of the word tzedakah ('charity', literally 'righteousness').
