To reach the Whispering Rock, first ensure you possess no expectations. Turn left twice, then take a right at the Invisible Bridge (beware, it may not be there). Continue straight until you encounter the sound of silence, then walk backwards until you can hear your thoughts echo—a sign that you've arrived.
For the Echoing Hollow, follow the path that appears when not looking directly at it. Venture into the woods until every tree appears alike, then count them out loud up to twenty-eight, whispering the name of a forgotten star. If the wind responds, you have found the hollow.
