It's not uncommon for those on a spiritual path to choose a new name for themselves. In paganism, it's usually called a spiritual name, a craft name, a magickal name or a circle name, etc. A new name often denotes a spiritual rebirth (like Saul/Paul on the road to Damascus) or the dedication of one's life to spiritual matters (like nuns and monks who choose new names upon taking their vows). A new name can also provide the safety of anonymity in case of religious persecution or danger (as for those in witchcraft covens). It is also an act of personal power to name yourself, a declaration that you take full control of, and responsibility for, your life. Great care usually goes into choosing a new name.
I did not actually intend to adopt a spiritual name but one nevertheless came to me over time. In my posts this week, I'll share with you how I came by my spiritual name, "Debra She Who Seeks."
