For as long as humans have been on earth, we have respected, deified, and worshipped animals. We celebrate their sacred powers and meaning, in rituals and festivities that continue to this day. Travel with us around the globe as we explore and explain our spiritual connection with horses and pigs. In Greek mythology, for example, the horse was a gift from Poseidon, god of the sea. Varaha, the third Avatar of the Hindu god Vishnu, took the form of a boar.
