Research has confirmed what the yogis of ancient times already knew: Profound physiological and psychological changes take place when we meditate, causing an actual shift in the brain and in the involuntary processes of the body.
This is how it works. An instrument called an electroencephalograph (EEG) records mental activity. During waking activity, when the mind constantly moves from one thought to another, the EEG registers jerky and rapid lines categorized as beta waves. When the mind calms down through meditation, the EEG shows waves that are smoother and slower, and categorizes them as alpha waves. As meditation deepens, brain activity decreases further. The EEG then registers an even smoother, slower pattern of activity we call theta waves. Studies on meditators have shown decreased perspiration and a slower rate of respiration accompanied by a decrease of metabolic wastes in the bloodstream. Lower blood pressure and an enhanced immune system are further benefits noted by research studies.
The health benefits meditation produces naturally reflect the mental and physical effects of this process. At the very least, meditation teaches you how to manage stress; reducing stress in turn enhances your overall physical health and emotional well-being. On a deeper level, it can add to the quality of your life by teaching you to be fully alert, aware, and alive. In short, it is a celebration of your self. You are not meditating to get anything, but rather to look at and let go of anything you do not need.
We highly recommend a period of daily meditation. Add it to the end of your asana practice, or set aside another block of time. The important thing is that you find a time that works best for you. Don’t do too much too soon; you’re apt to get discouraged and stop altogether.
To establish consistency, meditate at the same time and in the same place every day. Choose a place that is quiet, one that is pleasant, where you’ll be undisturbed.
Traditionally, the morning is considered the optimal time because you are less likely to be distracted by the demands of your day. Many people find that a morning meditation helps them enter the day with a greater degree of equanimity and poise. However, if a morning practice is a struggle, try an afternoon or early evening meditation.
If you are new to yoga and meditation, you may find adding five or 10 minutes of meditation at the end of your asana practice enough. When meditating independently of your yoga practice, a 15- to 20-minute time frame seems manageable for most beginners.
Choose a position that works for you. If you prefer sitting, either on a chair or on the floor, keep the spine erect and the body relaxed. Your hands should rest comfortably on your lap or thighs, with the palms up or down. If you choose to walk or stand, maintaining good posture is also critical, with your arms hanging freely by your sides. When lying down, place yourself in a symmetrical and comfortable position with the appropriate support under your head and knees if needed.
Decide on your point of focus. If sound appeals to you, create your own mantra, silently or audibly repeating a word or phrase that is calming to you, such as “peace,” “love,” or “joy.”
Affirmations also work. “I am relaxed” or “I am calm and alert” as you breathe out. Using a tape of chants or listening to a relaxing piece of music are also options.
If you choose imagery, visualize your favorite spot in nature with your eyes closed, or gaze upon an object placed in front of you: a lighted candle, a flower, or a picture of your favorite deity.
One way to observe the breath is to count it: Breathe in for three to seven counts and breathe out for the same length of time. Then shift to simply observing the breath, noticing its own natural rhythm and its movement in your torso.
Whichever posture and method you choose, stick with them for the duration of your meditation period. Indeed, once you find what works for you, you’ll want to maintain that practice indefinitely.
Do not be surprised or discouraged by how frequently your thoughts wander. When you realize that your mind has become distracted, simply return to your chosen point of focus.
At the beginning you might feel uncomfortable meditating—sitting for 20 minutes may cause your legs to fall asleep or cramp up, walking slowly may bring up feelings of impatience or agitation, and reclining poses may merely make you fall asleep. Conversely, you may have some profound experiences the first few times you sit, only to spend the next few frustrating days trying to duplicate them. Relax. Meditation shouldn’t cause you to feel unreasonably stressed or physically uncomfortable. If it does, reduce the length of your practice time or change your position (from walking to sitting; from sitting to standing). If that doesn’t work, go back to incorporating a few minutes of meditation into your asana practice instead of holding onto a formal practice. After a few days, try returning to your normal meditation routine.
If you continue having trouble with your meditation practice, you may need to seek the guidance of an experienced teacher or the support of a group that meets regularly to meditate together. Indications of your progress, with or without a teacher or group, are feelings of mental calm and physical comfort, and the ability to be present in all your experiences.
