The Tree of Life (Hebrew: עֵץ חַיִּים, ʿēṣ ḥayyim) is a symbolic diagram used in Jewish mystical traditions, especially in Kabbalah, to explain how the universe is organized, how life was created, and how people can grow spiritually. It is often called the "kabbalistic tree of life" to separate it from the tree of life mentioned in the Genesis story, which appears with the tree of the knowledge of good and evil, and from similar tree symbols in other cultures. This diagram serves as both a way to understand ideas and, in later Kabbalistic writings, as a visual guide showing how the sefirot, or divine forces, connect to the study of the universe and human spiritual growth.
Simo Parpola suggested that the idea of a tree of life with different parts representing different aspects of reality began in the Neo-Assyrian Empire around 900 BC. The Assyrians gave moral values and numbers to Mesopotamian gods, similar to those in Kabbalah, and linked these to sacred tree images as a model for the king, much like the idea of Adam Kadmon. However, J. H. Chajes argued that the ilan, or tree image, was mainly influenced by the Porphyrian tree and maps of the celestial spheres, not by ancient Assyrian or other sources.
Kabbalah began during the Middle Ages, starting with texts like the Bahir and the Zohar. Although the oldest surviving Hebrew Kabbalistic writings from the late 13th century include diagrams, such as one labeled "Tree of Wisdom," the now-famous tree of life design became widely recognized in the 14th century.
The first printed version of this image appeared on the cover of the Latin translation of Gates of Light in 1516. Scholars believe the artwork on the Porta Lucis cover was created by Johann Reuchlin.
Description
The Tree of Life usually has 10 or 11 nodes, which represent different main ideas, and 22 paths that connect these nodes. The nodes are often placed in three columns to show that they belong to the same group.
In Kabbalah, the nodes are called sefirot. They are usually shown as circles, and the paths (Hebrew: צִנּוֹר, romanized: ṣinnoroṯ) are shown as lines. The nodes represent broad ideas about existence, God, or the human mind. The paths show how the ideas connected to the nodes relate to each other or describe the steps needed to move from one idea to another. The three columns are often called pillars. These pillars usually stand for different kinds of moral values, types of energy, or kinds of ceremonial magic.
The sefirot are the ten spheres on the Tree of Life. Each sefirah (the singular form of sefirot) represents a different part of God’s nature, as well as parts of human thought and life. These are listed from top to bottom:
An eleventh sefirah, Da'at (meaning knowledge), appears in some diagrams of the Tree of Life halfway between Keter (node 1) and Tiferet (node 6).
The diagram is also used in Christian Kabbalah, Hermetic Qabalah, and Theosophy. The nodes are linked to gods, angels, stars, moral values, single colors or combinations of colors, and specific numbers.
History
Paolo Riccio's son, Jerome/Hieronymus, wrote letters and shared his father's work with Reuchlin before it was published. In 1516, Reuchlin's diagram appeared on the cover of Paolo Riccio's Latin translation of Joseph ben Abraham Gikatilla's Gates of Light. The diagram had 17 paths, and at that time, the ideas of 10 spheres and 22 letters were still separate in writings. In 1573, a version drawn by Franciscus Zillettus was included in Cesare Evoli's De divinis attributis.
This version introduced changes that later appeared in other diagrams: all spheres were the same size, lines became wide paths, spheres were arranged in three columns, Malkuth was connected to three spheres, and Hebrew names were paired with astrological symbols for celestial bodies. However, it still had 17 paths, arranged differently. Reuchlin's version was printed again in Johann Pistorius' work in 1587. Later, between 1592 and 1609, versions with 21 or 22 paths appeared in the posthumous editions of Moses Cordovero's Pardes Rimonim. These diagrams lacked consistency, and none included the 22 letters. Cordovero also described the paths in Pardes Rimonim, Gate 7, Chapter 1, and in Ohr Ne'erav, part 6, chapter 2. However, these descriptions disagreed about the arrangement of paths. Pardes Rimonim mentioned 24 paths, excluding two from Hod and Netzach to Malkuth. Ohr Ne'erav described 22 paths.
Between 1652 and 1654, Athanasius Kircher published his version of the tree in Oedipus Aegyptiacus. According to 20th-century occult writer Aleister Crowley, Kircher's diagram combined different ideas into one system. His version, called the Sefirotic System, added abstract ideas, divine names, the 22 Hebrew letters for each path, and new astrological symbols.
Between 1677 and 1684, Christian Knorr von Rosenroth published Kabbala denudata. The first volume ended with five ilanot, or kabbalistic trees, showing parts of Lurianic cosmology. Four of these were based on diagrams created by Jewish kabbalists in the previous 50 years. One (figures 8–12) was designed by Knorr based on his reading of Naftali Hertz ben Yaakov Elchanan's 1648 Emek ha-melekh.
Today, according to scholars of Western esotericism, two main versions of the diagram are widely used: one where Malkuth has one path, following Reuchlin's original, and another where Malkuth has three paths, following later versions. Both versions have 22 paths, each linked to a Hebrew letter, influenced by Kircher's work. With the rise of occultism in the 19th century, many new diagrams appeared, but they did not introduce major changes.
Jewish mystical (Kabbalistic) interpretation
Medieval Kabbalah, a form of Jewish mysticism, focused on creating symbolic models to explain the hidden structure of divine reality. This approach differed from earlier mystical traditions, which emphasized personal visions of heavenly places. Scholars describe this shift as a move from imagining the divine realm through direct experience to exploring God’s inner life using symbolic language, which cannot be seen directly and must be expressed through abstract ideas.
The Tree of Life, a key symbol in Kabbalah, was influenced by earlier texts like Sefer Yetzirah, which described creation as organized through concepts called sefirot and Hebrew letters. While Sefer Yetzirah did not fully explain the sefirot or provide a visual diagram, it introduced the idea that numbers, language, and divine activity are connected. This framework laid the foundation for later Kabbalistic symbols.
In Zoharic Kabbalah, divine reality is seen as active and dynamic, with God’s inner life expressed through processes like emanation and relationships within the divine nature. This view describes God as both beyond human understanding and internally complex, with creation and revelation as outward signs of God’s hidden energy. The sefirot in this tradition are symbols that represent divine activity, showing how God’s energy flows and connects with the world, rather than forming fixed diagrams.
Early Kabbalistic writings used various symbolic arrangements of the sefirot, such as lines, groups of three, and metaphors from astronomy and human forms. These symbols helped explain how divine energy flows from the infinite source to the created world, but they were not standardized diagrams. Later, medieval traditions combined these symbols into more structured visual forms, such as the Tree of Life.
In Chabad Hasidic interpretations, the Tree of Life is a complete model that connects the universe, human life, and spiritual practice. The sefirot are seen as steps in the flow of divine energy from the infinite source, Ein Sof, starting with Keter and extending to Malkuth, which represents the physical world. This model includes both the divine energy moving downward and the idea that human growth and moral actions move upward, reflecting a connection between the material world and the divine.
Anthroposophical explanation
In 1924, Rudolf Steiner gave lectures to workers in Dornach. He explained the Tree of Life and its sephira from a broader perspective, considering both tradition and ancient knowledge.
The Sephiroth tree contained the highest wisdom of ancient Jewish people. It also showed how humans relate to the world. It has been emphasized that humans are not only made of visible parts, like the body, but also of invisible, non-physical parts. These parts include the etheric body, the astral body, and the ego. These ideas were known in ancient times, though people understood them instinctively rather than through study. This knowledge has been completely lost. Today, many believe the Sephiroth tree is a fantasy, but it is not.
Steiner explained that the sephira represent forces acting on humans from the cosmos or Earth. He used descriptive words to explain what ancient Jews meant by these terms.
To understand the Sephiroth tree, consider this: Humans exist in the world, and forces from the world act on them from all sides. Three forces affect the human head, three affect the chest and areas related to breathing and blood circulation, three affect the limbs, and a tenth force comes from Earth.
The head, along with the sensory system and nerves, is connected to three terms: Kether (crown), Chokmah (wisdom), and Binah (intelligence).
Next, three forces influence the middle part of the human body, where the heart and lungs are located. These forces are more connected to the environment, such as sunlight, wind, and weather. These forces are called Chesed, Geburah, and Tiphereth.
Three other forces relate to the astral body. Netsah refers to the ability to overcome the firmness of Earth, allowing movement. Hod relates to human reproduction and is connected to compassion.
