Yes, it is possible! There isn't just one way to change your perception. Some changes come from an array of unforeseen external experiences, but if you are looking to consciously shift your perception the most important aspect of that is to "choose" to shift it. Affirm daily that which you wish to perceive...feel the change, see the change, and believe the change. You can do this by picturing your body receiving and accepting these new perceptions. Begin to embrace and live life in accordance to what you now seek and envision for your life.
