The planetary seals and kamea can be used in any work that is governed by that particular planet. You can use them as symbols drawn out and placed on your altar or you can inscribe them on amulets or talismans. The intelligence and spirit of the planet can also be used. The intelligence is generally considered for good or positive work, and the spirit for evil or negative work. When working with these forces, you want to call them from the highest level down; i.e. start with the Divine name, move to archangelic, then angelic and finally planetary names. You also want to have a clear focus of what you want so that you can send a clear mental image to the invoked entity.
