The Katha Upanishad puts it this way: “God made the senses turn outwards, man therefore looks outwards, not into himself. But occasionally a daring soul, desiring immortality, has looked back and found himself.” In fact the “daring soul” doesn’t lack encouragement. He’s surrounded by countless reminders and opportunities, countless means of reversing the arrow of attention - if only he’s sufficiently inquisitive about his true identity, and if only he’s willing to drop for a moment opinions about himself based on hearsay and memory and imagination and to rely on PRESENT EVIDENCE.
