Botsina

Botsina means lantern, lamp, torch, or spark in Aramaic. Often in Jewish sources it refers to causes of spiritual enlightenment.

Use in Jewish mysticism

The initial essay in the Zohar, known by its initial Aramaic words Bereish Hormanuta D'malka, uses the phrase botsina dikardinuta to describe what is explained in early Lurianic texts as an "explosion within thought". This phrase is associated in various streams of Jewish mystical thought, however particularly in Hasidism, with the kav hamidah''.''
Pinchas Giller devotes a section of Reading the Zohar: the sacred text of the Kabbalah to the phrase, calling it "the boldest image of the Hormanuta literature". Yehuda Liebes writes that "ambiguities of meaning are typical in the Zohar, and the word bostina illustrates this well".

As a descriptive term for Torah sages

Rabbi Shimon Bar Yochai, traditionally the author of the Zohar, is referred to as botsina kadisha. The Arizal is referred to as botsina kadisha in the books of his disciple Rabbi Chaim Vital, as is the Alter Rebbe of Chabad in the opening of his book Likkutei Torah.
