There’s no single right way to choose your magickal name, but there might be a less-right way.
One of my friends says that taking a phrase that encapsulates your fantasy of who you want to be (and maybe sticking “Lady” or “Lord” in front of it) gives you a great cosplay name, but can put your ego in the way of your spiritual growth.
I don’t know. It’s worth pondering.
When I chose the Wiccan path, my name was revealed to me in a dream. When that name no longer seemed right, I asked my friends for a new name. One of them named me, but I could never remember it – because the name wasn’t about me; it encapsulated his fantasy of me. Eventually I went into the woods and prayed for a name. Nature responded instantly. I have carried that revealed name for decades now.
For things magickal, I’m a huge fan of letting the Universe decide, because that’s what works for me. Your way may involve divination, meditation, numerology, astrological calculations, or any number of other methods, which are all equally valid because each of them works beautifully for someone.
Maybe the most important choice we make is choosing how to choose.
