Meditative self-inquiry is the art of asking a spiritually powerful question. And a question that is spiritually powerful always points us back to ourselves. Because the most important thing that leads to spiritual awakening is to discover who and what we are—to wake up from this dream state, this trance state of identification with ego. And for this awakening to occur, there needs to be some transformative energy that can flash into consciousness. It needs to be an energy that is actually powerful enough to awaken consciousness out of its trance of separateness into the truth of our being. Inquiry is an active engagement with our own experience that can cultivate this flash of spiritual insight.
