You wrote two posts, which means you have to ask three words instead of four. The post station is a post horse, which means that you love to go well and you want to go well. If you don't get better, you will have good luck. If you can get in, there will always be opportunities around you, and so on. If you are a god, you will often be surprised. If you don't care, riots, financial ruin, sudden changes and so on.
