Anam Cara refers to the Celtic spiritual belief of souls connecting and bonding. In Celtic Spiritual tradition, it is believed that the soul radiates all about the physical body, what some refer to as an aura. When you connect with another person and become completely open and trusting with that individual, your two souls begin to flow together. Should such a deep bond be formed, it is said you have found your Anam Cara or soul friend.
