The Qabbalah or tree of life is called Etz Ha-Chaim, which comes from the Hebrew and means receiving, accepting.
The Tree of Life is mentioned for the first time in Genesis (first book of the Jewish Tanach and the Christian Bible).
It uses symbols to summarize every human force - the soul (microcosm) and the universe (macrocosm) - in a diagram. It is a so-called glyph. A graphic representation of a character. It is the representation of the universe in a diagram.
With this tree it is possible to illuminate and perfect our different aspects in our soul. For example, in meditation you can also use it to balance opposing elements in your being.
But ultimately, the tree is the core of the Western mysteries. Through study, we gain knowledge about the nature of creation and the human soul. Here we find everything that exists. From the highest spiritual dimension, to matter.
The individual points on the tree are called Sefirah, plural Sefirot, these are the objects in the tree, they show us what it is about. All Sefiroths are interconnected with paths. These paths are the subject in the tree, that is, how we get from one Sefirah to the next.
There are 10 Sefirot in number. Only the lines alone count 22. Overall, with the ten Sefirahs there are 32 development paths on the tree.
Each Sefirah symbolizes an essential principle of existence.
These 22 lines fit the 22 Hebrew letters and also the 22 trumps in the Tarot. In astrology, the individual planets are assigned to the Sefirot and here we also find the Little Arcana of the Tarot.
Thus, it is clear that the tree is the common thread through these three systems, and in this way we are looking at the entire universe from different angles.
