I can't recall the time, but I remember reading about using your own body as a pendulum. I tried this today and I have to say it does work! But before I tell you about my divination, let me just explain this to you: it's very simple and easy.
You'd better meditate before this and calm your mind. Then stand up and make sure your stand is firm and that you stand in the middle without leaning back nor forward.
Then, you can close your eyes if you want to (I found it easier at first). Center your mind and ask a question. After the question you should feel the tendency to - and in fact, your body starting to lean either back of forth. if you body leans forward the answer is YES, if you body leans backward the answer is NO. Simple, right? Si, senor!
This is great technique if you feel like a regular pendulum doesn't work for you, or if you worry that you move your hand accidentally.
I asked if there's a soulmate for me out there and felt my body pulling strongly forward. Then I asked if this particular interest of mine would be the right person, I felt my body pulling itself back. So apparently there's someone much more suitable for me out there. :) But how are we going to find each other is yet another story...
