Does it ever happen? I believe that, sometimes, it does.Two people meet, and it is as though they are "struck with a thunderbolt". It is instantaneous. They "know"!
Gay men know each other, instantly.
I believe that the same thing happens with a Mentor/Teacher. I made a comment on another post that you don't find a teacher; "the teacher finds you". It rarely happens, but it does happen. An experienced witch can spot a potential student, instantly.
One sees a young boy or girl, and they have a "stillness" about them.They seem to have "open eyes" that miss nothing! They are "aware"; they "know".
Witches can always recognize another witch. It happens to me, quite often. Yet, I am a very ordinary looking man.There is nothing unusual in my dress or bearing.
In the nearest town to the village where I live there is a "magic" shop. I first entered that shop when I first came to live here,eleven years ago.
Although I was the first customer at the counter, the shopkeeper smiled and asked if I would mind if she served the lady behind me. I nodded, alright by me. The lady had a little girl with her and was buying a Halloween costume. When the lady left the shop, the lady behind the counter said,
"We have a good selection of incense. Natural Frankincense."
I asked her how she knew. She said, "It's in your eyes! I knew you were a witch as soon as you walked into the shop."
I gave a little laugh, "Yes! I knew you right away!"
It has happened many times over the years. It is why I believe that a student should not really look for a teacher. The teacher will find the student!
