Crystals may be used to move energy from the mental body out into the aether to contact your spirit guides for help and get answers. The cosmic phone call is one way in which to contact your spirit guides and get answers.
By placing the quartz crystal with the point away from you in your dominant hand and another quartz crystal with the point towards you in your non-dominant hand, you can transmit energy out of you and receive answers with this technique.
If you are right handed, your dominant hand is your right hand and your non-dominant hand is your left hand. If you are left handed, your dominant hand is your left hand and your non-dominant hand is your right hand.
