Like the moon waxes and wanes, your energy level and mood changes with every monthly cycle. These changes relate closely to the stages of your menstrual cycle. Ancient yogic teachings say that a woman has 11 moon centers on specific parts of the body. As you move through the month, energy concentrates in one moon center and shifts after 2.5 days. Similarly to the chakras, every moon center influences your mood, decisions, feelings, values and how you process the world.
