Beautiful, Colorful, DNA Tree of Life. The Tree of Life symbol represents our personal development, uniqueness, and individual beauty. Just as the branches of a tree strengthen and grow upwards to the sky, we too grow stronger, striving for greater knowledge, wisdom, and new experiences as we move through life. In my own version of the tree of life, I use the colors of the chakra to represent the energy and vibration that flows through us, and how this energy evolves and grows enhancing our spiritual growth. DNA has quantum and interdimensional aspects to it. Therefore the DNA represents spiritual evolution.
