A wise king wanted advice about what to do when he faced a real crisis in his life. He met his master. The master gave him a locket and told him to open it only when he was in difficulty. After some years he was defeated in a battle and he lost his kingdom.
He was worried and was hiding in a cave. He suddenly remembered what his master had told him. He opened the locket and there he found a note, "even this will pass", and a second note which said, "if one door closes another door opens". He gained strength from this piece of advice and after a month won his kingdom back. He went to his master and thanked him and asked a question: "Why does the door close?" "The door is always open, your mind is closed," replied the master.
There are two types of worlds we live in. The visible world and the invisible world. The outer world and the inner world. Our body is in this outer space but our mind is in another space. Just as our body gets dirty if one is in a dirty space our inner self, our mind, gets dirty if we visit dirty areas in the inner world. If one broods over worry, dislike, anger, jealousy, then our mind is polluted. With such pollution you find the outer world a pain. The real pain is when our mind lives in negativity.
What type of world are we in? This is what one should really be aware of. Where are we placed psychologically is what we have to watch for. One believes that the outer world is the real world and not the inner world of mind.
