Sometimes I get angry. Sometimes my thoughts fire so rapidly that it's difficult calm my brain down. Meditation has been the most useful tool in soothing this crazy head. Not only does it relax me, but it gives me fresh perspectives on any problems I'm facing. If something's bothering me and I can't figure out how to fix it, meditating helps me because it clears out the clutter of disorganized thinking. It gets me in touch with a higher spiritual power that somehow knows what the wisest decision should be in any given situation.
It's kind of like rebooting a computer after it crashes. When the brain "crashes", we need to do the very same thing to restart it. Most people take a break or a nap, but those who are more spiritually aware engage in the powerful practice of meditation.
An additional benefit is that the more you meditate, the more you get in touch with that higher spiritual power in everyday life. If you start out doing it every day, you'll soon be meditating less, because the mindfulness that results makes you more consistent in dealing with your problems calmly. However, it's still worthwhile to practice daily, lest the clutter catches up with you and dethrones all the calmness you'd built.
Meditation works by focusing on something that relaxes you and holds that thought in place for at least 10 minutes. This helps the mind slow down and get "in tune" with the universe. You can be laying down or sitting up, it doesn't matter. Buddhist monks practice meditation in several lotus positions, which is more difficult to do, but (I've read) it does a better job connecting you with the spirit.
The books have taught me several ways of doing it. The method that works best for me is imagining a symbol like the yin-yang or seven chakras, and just focusing on that image until all thoughts disappear and the brain more or less stops functioning. That is the ultimate objective of meditation: to get the brain to stop thinking. That's why the environment must be silent, because any distractions will lead the mind astray, interrupting the practice. Another way to do it is by letting your thoughts wander, like in a dream. But I've found this doesn't work as effectively as restraining all thought.
Nothing can make you feel more connected, peaceful, and ready to face your problems than meditation does. Once you come out of it, you'll immediately feel a greater awareness with all that is around you. You might even feel invincible, like nothing can stop you, but not in a competitive way, just as a receiver of life's problems. If you feel like your spirit is broken, or like you are disconnected from the world, nothing will bring you back faster than doing meditation. Discipline your mind today, and you'll reap the rewards tomorrow.
