The Tree of Life (Etz Chaim) first appears in the Torah within the creation narrative in Genesis. Planted at the heart of the Garden of Eden, alongside the Tree of Knowledge of Good and Evil, it is described as a source of eternal life: “The Lord God caused to grow… the Tree of Life in the middle of the garden” (Genesis 2:9). Unlike the Tree of Knowledge, whose fruit Adam and Eve consumed, the Tree of Life was not touched, leaving its mystery intact.
The Ramban interprets the Tree of Life as representing immortality, noting that eating from its fruit would have granted eternal life. In contrast, the Tree of Knowledge introduced moral complexity and the concept of choice. This duality finds echoes in later Jewish thought, where the Tree of Life is subtly associated with the afterlife and the continuity of the soul.

Interpretations Across Time
Rabbinic literature and the Medrash offer various insights into the Tree of Life. It is often seen as a metaphor for Torah, the eternal wisdom that sustains life. Proverbs 3:18 famously states, “It is a tree of life for those who grasp it, and those who uphold it are blessed.” This verse is recited during the Torah service, underscoring the connection between the Tree of Life and the Torah.
The Zohar, a foundational text of Kabbalah, delves deeply into its mystical dimensions, portraying it as a conduit between heaven and earth, linking creation to the divine. The Zohar describes the Tree of Life as a source of divine light, symbolizing the harmonious flow of spiritual energy.
