Meditation isn't thinking about things, but it's also not about trying to not have thoughts. Your mind secretes thoughts like your stomach secretes enzymes, so to try to stop the thinking process is only going to create frustration and an antagonistic relationship between yourself and your own mind, which is a painful way to live. Thinking is what the mind does, so it's certainly going to happen when you sit down to meditate. So don't fight it. Meditation isn't at all about fighting. But it's also not about just sitting there and thinking about things, getting lost in our daydreams and worries and plans for the future. The thoughts will come, and in meditation we practice letting go of the need to follow each and every one of them. We practice letting go of the thoughts. Sometimes it can feel like the thoughts are having us instead of us having the thoughts. And that sometimes, we are just along for the ride. We practice stepping off that ride in meditation. We practice paying attention to what we want to be paying attention to, when we want to paying attention to it. So instead of paying attention to the ten-thousandth time you've had the thought, “I shouldn't have said that thing to my co-worker”, we let that thought arise, and then practice letting it move on through by coming back to the object or the focal point for our meditation. In many meditations we can follow, the object or focal point is the different experiences of the body, in a breathing meditation it's the feeling of the breath, in an eating meditation it's the experience of eating, and so on. And in so doing, we develop a certain skill not only with letting go of some of those endless and un-beneficial thoughts, but also with paying attention to what we want to be paying attention to. And that's the true hallmark of meditation, a sense of choice as to what the mind is paying attention to, and a sense of bright attention or awareness. There is so much to learn and gain around the science of mindfulness, more than you can get from a short written lesson. Therefore, to get the most value and benefit, you need to begin the practice of meditating. Practice is the operative word. We can only become better at what we practice. A great way to begin the practice is with an app called Headspace (headspace.com). It has both free and paid for mediations for you to listen to and practice.
