Crow speaks of Natural Law.
If you throw a stone up, it must come down.
If you hear lightning, there will be thunder.
According to Jamie Sams and David Carson, Crow is the left-handed Guardian, and his eye is the gateway to the supernatural. He knows the mysteries of creation, and is the keeper of Sacred Law.
Crow can bend the laws and shape-shift, like Raven
Crow sees himself in the mirror, and can double, or be in two places at once consciously. He can observe what is far away. He observes with one eye at a time, one eye seeing the present, the other seeing the void. Crow medicine people are masters of illusion, and all sacred texts are under the Protection of Crow, bound to Crow feathers.
Crow is also an omen of change, and can see past, present and future.
Crow invites you to align yourself with the Laws of Great Spirit, and speaks to council you – as well as help you communicate with Great Spirit.
