It is believed that everything on Earth is influenced by the energetic rays of The Seven Planets. Everything that exists – metals, minerals, gem stones, plants, animals and also humans – consist of an intertwined energetic combination of The Seven Planets, The Five Elements and The Three basic Prime principles. As a result, it is the combination and balance of these energies that determines what will emerge and what kind of character it/we will have.
Working with the planets is to change how the flow of these seven life energies can be transformed by outer and inner influences, and how this flow can be supported and cultivated.
In conclusion, a lot more can be said about each of The Seven Planets of Alchemy and what they govern and represent. But this page should give you a basic overview, and enable you to start working with the planets in your spiritual practice.
