Lost in space

As you walk the way of the sand dune you realize it is much farther than it had looked and consider turning back. Then you think of the riches that lie below you in the sand dune and push onward. When you finally reach the dune all you can think about is the gold and treasure that lie below you just in the hole of the dune. You decide to enter the dune and start the journey down. As you walk down the steep steps you stumble every once in a while and finally make it to what looks like the bottom but you are wrong it is not the bottom. As you step onto flat ground walls shoot up all around you and a sword falls from the ground and a giant spider with fuzz on his legs and fifty six eyes on its head all looking directly at you. You realize what it is, you have read all about tests for worthiness to enter special areas. This was one of them. As you grab the sword you know what to do. You swing the sword a couple of times to test the durability and flimsiness. Ad you swing the sword you accidentally stab the spider in the head. “ Good luck I guess,” you think. The walls fall down and you see how much farther down the steps go. The stairs go for about another three miles. Do you keep going or turn back?
