1: Breath: Breathe naturally, without forcing anything. Notice the sensation at your nostrils, and the rise and fall of your chest and belly as you breathe. When your mind wanders, gently bring it back to your breath.
2: Posture: Feel free to sit cross-legged, kneel, sit on a chair or lie down — whatever's most comfortable. The most important thing is posture: Your back should be straight but not rigid, so imagine that you're being pulled toward the sky with a string attached to the crown of your head. Try not to fidget or squirm; instead of immediately reacting to discomfort, be aware of how it affects you.
3: Eyes and tongue: Close your eyes, keep them open or leave them half open, but pick one way and stick with it throughout the meditation. To stabilize your tongue, rest it lightly on the roof of your mouth. This Zen technique is believed to cut down on subvocalization, which is when your tongue moves slightly with the thoughts that pass through your head.
4: Routine: You're more likely to incorporate meditation into your daily routine if you have a designated time and spot for it. Pick a quiet corner in your home, and turn off electronics. Mornings are good, before you drink any coffee so you're not wired. Try not to meditate after a heavy meal or just before bed because you tend to be sleepy. Set a timer to alert you to the end of your session to frame the meditation and give it a ritualistic quality. Aim to meditate at least five days a week; there's not much benefit if you do it once a week or every now and then.
5: Time: Meditating 20 to 30 minutes daily is ideal, but if you only have five or 10 minutes, go for it. There is no "right" way to meditate, so let go of goal orientation, and don't try to track your progress.
