Meditation means different things to different people, but there remains a common thread: meditation is about bringing your whole self together, aligned and powerful. Some people chant, some people may perform yoga or tai chi, some people simply sit in silence. The means of doing so isn’t important, as long as it works for you.
For me, I usually meditate with quiet. I let my mouth go quiet, my brain, and finally, my emotions. I try to let myself be as open as I can, letting emotions flow out of me and peace flow in to me. I let all my muscles relax, and just generally let go of all the little stresses I have been keeping inside.
In reality, I don’t even do this every day, though I really should. In fact, in an ideal world, I would probably do it at least two or three times each day. Ten minutes spent meditating (how long you need varies, even in an individual) is usually enough of a performance and mood boost that you get vastly more done in a day than you would have had you spent those ten minutes working on something.
So try meditating. Try one technique, and if it doesn’t really work for you, try another. Once you find one that DOES work for you, you will soon be wondering how you went without it for so long.
