Do not be deceived by your past experience and knowledge, nothing is inherently good or bad. If you desire things in this world, do not let your mind tell you we should only pursue spiritual things rather than earthly things. You desire more, because you are capable of having more. Earthly things is just another aspect of the spiritual. Ask yourself quietly and deeply till you feel it: What is that you really want? And know you already have it. That's the secret.
