And out of the ground made the LORD God to grow every tree that is pleasant to the sight, and good for food; the tree of life also in the midst of the garden, and the tree of the knowledge of good and evil.
My son, forget not My instruction, and may your heart keep My commandments; [...] It is a tree of life for those who grasp it, and those who draw near it are fortunate.
The term Etz Chaim (plural: עצי חייםAtzei Chaim) is also used to describe each of the wooden poles to which the parchment of a Sefer Torah is attached. A hymn including the aforementioned verse Proverbs 3:18 (Etz ḥayim hi lamaḥaziqim bah, v'tomkheiha m'ushar) is sung in all Ashkenazi rites as the Torah is returned to the ark.[1]
In Kabbalah, the Etz Ḥayim symbol (Etz Ha-Hayim, The Tree of Life") is a mystical symbol used to understand the nature of God and the manner in which he created the world. The term Etz Ḥayim is also the title of one of the most important works in Jewish mysticism, written by Ḥayim Vital in the course of twenty years following the death of his master, Isaac Luria, in 1572, presenting and explicating Luria's systematic reconceptualization and expansion of the insights of the Zohar and other earlier mystical sources. Vital's Etz Chaim is the foundational work for the later Lurianic Kabbalah, which soon became the mainstream form of Kabbalah amongst both Sephardi and Ashkenazi Jewry up to the modern period. This massive multi-volumed work circulated only in manuscript form among mystics for over 100 years, and was first published in 1782.
