As the same of the Seed of Life suggests, it is the basis for all creation, and the universe as we know it. One thing builds on another, and it creates the next layer, and the next.
The Seed of Life can be used as an aid to help you keep yourself balanced, and to center yourself no matter how chaotic things get in your life. As a meditation aid and point of focus, the Seed of Life can allow you to remake yourself, following the creation of new internal universes. By focusing on the seven circles, and the journey through each, you fill yourself with the energy represented by the seed, and allow it to regrow and replace energy you have spent, leaving you refreshed and feeling like you've begun a new cycle.
