Crystals can help you connect with your spirit guide (or anyone else, for that matter) if you programme them to do so, and then use them in meditation or journeying.
The first step is choosing a crystal that helps open the third eye, such as lapis lazuli, sodalite or amethyst.
Next, you attune yourself to the crystal: after grounding yourself, you hold the crystal in your non-dominant hand until you feel its pulse or vibration (make sure it's not your heartbeat you are feeling: check your own pulse first to tell the difference). Once you feel the pulsation of the stone, place it on your third eye, and "draw it in" - that is, feel the vibration of the stone coming into you on the in-breath, and spreading throughout your body. Once you've done that for a few minutes, start feeling how your own body is taking the vibration of the stone, and can project it out on the out-breath. Working like this with your breath and the pulse of the stone, you start feeling how your body, mind, breath and the stone are all working together.
Once you've reached that (it sounds complicated but it isn't - it shouldn't take you more than 10 minutes) - you can start programming your stone. This time holding the stone in your dominant hand, project the image/sound/feeling of what you want to achieve into the stone. Work with your breath and the vibration of the stone and of your body as before. Do it until you feel the stone responding. You should feel a subtle change in vibration. Thank the stone
Once you are attuned to your stone and have programmed it, you can now use it to connect with your spirit guide in meditation (or, if you practice it, shamanic journeying), by setting out the intent to encounter your spirit guide as you settle into your meditation. You can hold or tape the stone on your third eye as you do so, and keep it there during the whole meditation. You can encounter your guide in different ways: you might see him, feel his energy, hear him, smell him, feel his touch, or any combination of the above - keep your senses alert and don't prejudge how he will manifest himself to you.
Good luck! It's always worth meeting a dashing man on a horse, if only in spirit form!
Oh - one last thing: don't do any of this during a moon void of course - the time between the last aspect of the moon in one sign and when it enters the next sign. It's not an effective time for manifestation.
BTW - using a pendulum is dead easy! You just hold it and ask questions, having established what it would do for yes and no.
