The bowl is engraved twice: the flower of life and the staff of Hermes. The flower of life is the sacred universal symbol for many traditions. Inside, it contains all the constructions of the universe and all the structures at the base of life. The starting point of the Flower of Life is a central circle that symbolizes the original point, the seed, the source of all life. The basic figure, composed of 7 circles and called the Seed of Life, perfectly illustrates the development of life from a single core.
The Staff of Hermes or Attribute of Hermes (Mercury), originating from the myth of Hermes, is a symbol of peace and neutrality in the balance of opposing forces. It consists of a rod surrounded by two intertwined serpents, topped with two short wings. It achieves the balance of opposing tendencies around the axis of the world or the axis of life (the serpents representing fire and water, the rod the earth, and the wings the sky). The caduceus became a symbol of mediation and peace carried by the "Messenger of the Gods" and also, for the initiates, the guide of beings in their changes of state. It is also a symbol associated with Kundalini. It is, of course, the caduceus of the health professions!
