Hold the crystal in your dominant hand and clear your mind of any negative or unwanted thoughts. This may take time at first, but it will get easier with practice.
Still your mind and begin to focus on your crystal and the intention you have chosen for it. Describe your intention aloud or in your mind, and repeat these words until you feel this energy has connected with the crystal. Your intuition will tell you when the intention is set.
Keep your crystal in your pocket, on your desk, under your pillow, or next to your bed to serve as a constant reminder of the positive intentions you have set. Revisit and reset your intentions weekly to continue on your positive journey. Stay conscious of the energy you are bringing in. Be positive, and positivity will come to you.
