A spiritual teaching is a finger pointing toward Reality; it is not Reality itself. To be in a true and mature relationship with a spiritual teaching requires you to apply it, not simply believe in it. Belief leads to various forms of fundamentalism and shuts down the curiosity and inquiry that are essential to open the way for awakening and what lies beyond awakening. A good spiritual teaching is something that you work with and apply. In doing so, it works on you (often in a hidden way) and helps reveal to you the Truth (and falseness) that lies within you.
