Concentration is the ability to pay attention. Do you ever sit down to talk to a friend and notice that your mind gets pulled in a million different directions? You start thinking about a problem at work or planning a project at home or checking your smartphone. Concentration is the opposite of that. It’s being able to focus on what you want to focus on. Concentration is probably the most useful skill you can possibly develop, because it helps you do everything better. Can you think of anything you do, work, or school, or in your personal life, that wouldn’t go better with concentration?
Sensory clarity is the ability to zoom in on the individual components that make up your experience. Instead of feeling angry, for example, you learn to track the mental images, the mental talk, and the emotional body sensations that make up this thing we call angry. By detangling this experience, you can learn to manage it much better, and weirdly enough, you’ll find that not only does this zooming in make the unpleasant experiences less overwhelming, but it also makes the pleasant experiences more satisfying.
Equanimity is a little trickier to understand, but it essentially means that you allow yourself to experience without trying to push things away or grasp onto them. For example, when something unpleasant comes up, you don’t try to suppress it. When something pleasant comes up, you don’t try to hold onto it. Equanimity means not interfering with your own internal experience. Increasing your level of baseline mindfulness can lead to all kinds of good stuff: less suffering, more fulfillment, a deeper knowledge of who you are, positive behavior changes, and even the ability to help other people more effectively.
