Blue Sapphire can help you gain self-mastery—that is, mastery of your mind, emotions, and physical body. To understand how Blue Sapphire does this, it’s necessary to understand certain aspects of the mind. The mind is complex and comprised of many levels, or areas. Thoughts are formed at the highest level of the mind—that which is closest to your purely spiritual aspect. There, thoughts are generated continually; indeed, a new thought is born every moment. Ultimately, you have the power to discriminate and choose which thoughts you wish to have. This is an important choice, because your thoughts feed and otherwise profoundly affect your emotions and physical body.Blue sapphires help in certain alternative medicines and even some actual science.
