Here is the most simple and easy pendulum method that I know.
Grip the chain and lift the pandulum up keeping you hand has relexed has you can.
Now simple ask the pendulum some simple questions.
Show me your yes
Show me your no
show me your not sure
For each of the questions take notice how the pendulum moves. for example.
do's it move back and forwared or left and right or does it move round in a circle.
When you have done you will be read to ask your questions.
They are many more methods that can be used with the pendulum like using it with a map to find things.
Good luck I hope this easy method is of some help to people just starting with using a pendulum.
