The acquirement of spiritual wisdom does not necessarily prevent us from making worldly mistakes; but because it develops the qualities that will prevent them, and because it takes to heart the lessons of experience, humbly and receptively, it does reduce the frequency of those mistakes.
Being your true self, being your true nature, is different than experiencing it with thought. Realize that you are the mystery, and you can't really look at mystery because you are only capable of looking from the mystery. There is a very awake, alive and loving mystery, and that is what is seeing through your eyes at this moment. Encounter pure mystery, which is pure spirit, and wake up to what you are.
