The answer is simple:
You discover your purpose by being present in the moment. Listening to your inner guidance. Paying attention to the messages you are receiving at any given time. Being aware of the feelings in your body when certain things awaken a desire within us. And being absolutely mindful of our thoughts. If purpose is within us, and you desire to discover consciously what your purpose is, then we must understand that spirit speaks to you in present moment. You cannot hear the message from spirit when thinking about the past or thinking about the future. Spirit speaks to you in present moment. It is a now experience.
