Doing Pendulum Readings for Others
Until you have had a lot of experience with the pendulum, do NOT try to use it to get information for someone else. There are ways to do this but it is difficult because the information comes from inside the person using the pendulum, and in order to use the pendulum on behalf of someone else, you have to be very tuned into the other person. Anyone can use the pendulum for himself, but few can use it for others. So don't do pendulum readings. Instead, make it a personal tool for yourself.
Things that can Cause an Incorrect Response from the Pendulum
Poor communication. (inaccurate phrasing) The most important thing is how you phrase the question. For example, don't just ask "Is this water good for me"?" Be more accurate: Good in what way? The water may have both good and bad aspects. For example, you may be extremely thirsty, so the water is good for replenishing your body fluids, but the water could be tainted and later give you diarrhea. So state the question more clearly such as "Will this water serve my highest and greatest good?"
Asking questions that are too general: Don't ask general questions such as "Is Mary healthy?" Rather ask specific questions such as "Is Mary's diet causing her health problems?"
Being tired.
Forcing the situation. Using the pendulum even though the time or circumstances may not be right.
Being off Center: Feeling mentally or emotionally out of balance. You need to be in the right frame of mind.
Focusing too heavily on the pendulum itself, and not enough on the information inside you.
Being too close to high frequency electrical equipment (operate at least 3 ft from a TV or computer screen).
