Eir ("mercy") is a Norse Goddess of Healing. She knew the secret powers of herbs, with which she could even resurrect the dead. Patroness of shadow workers, called on against sickness or injury. She gives both physical and psychic means of healing; shamanic healing, especially, falls into her realm. Eir is a companion of the goddess Frigga.
Cycles of the Moon and Setting Intentions: When the moon is full or brand new is an especially good energy for setting intentions and meditation. New intentions come in with the new moon and what you don't want to focus on any more goes out with the old moon as it reaches its fullness. This sets a rhythm for your yoga practice.
