There are usually two different depictions when it comes to the tree of life and I took a shot at both of them over the years.
The first one is the more traditional version depicting a relatively realistic looking tree. This tree of life is a symbol of a fresh start on life, positive energy, good health and a bright future. As a symbol of immortality. A tree grows old, yet it bears seeds that contain its very essence and in this way, the tree becomes immortal.
The second version is according to Kabbalah teachings a relational matrix of ten divine emanations through which God creates, sustains, and directs all worlds. The Tree of Life is holographic and ongoingly creates reality, sustains all worlds in each and every moment, and directs and holds everything with universal law and the Ever-flow of Abundance.
The Kabbalah version of the tree is very abstract, geometric and strongly intertwined with the Flower Of Life.
To close it out a moving eye candy version of the traditional tree.
