Counterpart to the Empress, the Emperor signifies a powerful influence, generally male in nature. This can also include concepts in your life historically considered masculine, such as leadership and authority, self-discipline, and stability through the power of action. Its positive influences suggest you may be on a path to advancement or promotion, but it can also be neutral. Often a companion to those destined to take on greater responsibility, it may indicate change or loss that necessitates you stepping forward to shoulder a greater burden than you have in the past. Whatever the driving force for the change, it indicates you may possess an uncommon inner strength that will compel you act and to lead.
