How did it feel? It was exhilarating, intimidating, scary, enlightening, and more. My heart raced and I wanted nothing more in that moment than to continue doing readings to see my entire world spelled out. But it is not so much about unlocking your potential, as realizing you are interpreting things in a certain way. You are learning to ask questions in a way which works with the method of divination.
Outside of attempting scrying, I first practiced divination with a pendulum. I had one which gave be very accurate results, but that was lost in a strange transition in my life. I have not since had success with a pendulum.
I've also used tarot, to some greater and lesser successes.
Some things to consider is that sometimes the question affects the answer, and sometimes the advice comes about something broader than is being asked. So keep an open mind.
