Recharge yourself, hold a crystal in your hand. For best results, hold two crystals in both your hands to allow for energy current to flow into your body and out, completing a circuit. You do this by holding a crystal pointing outwards with your right hand, and while the left hand holds another crystal pointing inwards towards your body.
You can use crystals to hold energy in a room, help pick yourself up, and help others who need an energy shift. You can also use different crystals for the individual chakras, or energy centers and practice chakra balancing.
