Citrine harbors the power of the Sun. Citrine enhances optimism, self-esteem, and self-confidence. To receive the most benefits Citrine should be kept in contact with one's skin. This crystal is small enough to be held in your hand or kept in your pocket. It is a cleansing and regenerating crystal and that would explain why it would benefit a Reiki Professional. It can be placed on your client or held in your hand during your sessions. This is one crystal that rarely needs cleansing.
