Svadhishthana is illustrated as a white lotus. It has six vermilion-colored petals. Inside this lotus is a white crescent moon which represents the water region. Western occultists make the kabbalistic association of Svadhishthana with the Sephirah Yesod. Yesod is also associated with the sexual organs. Its function in the tree of life is to gather the different energies that have been created in the descent of the tree downwards and distribute them to Malkuth, the material world, where the energy can find physical expression. It is influenced by Mars. It is in the sympathetic nervous system. The alchemical metal is iron. The color associated with Mars is red. Each Incense brick is enriched with various natural ingredients including aromatic woods, exotic flowers, natural barks, tree and tree extracts, resins, leaves and flowers.
