Sulfur quartz has the power to bring about extreme transformation, by fostering self-esteem and developing intuition. These transformations can be seemingly simple, but the spiritual power they hold is in your ability to express and maintain your ideas. Write down an affirmation of something you want to express more freely. Plae your sulfur crystal over the affirmation and meditate with it in front of you. This will help you gain the self-esteem you need.
