The most basic form of meditation involves attending to one's breath

Begin by sitting in a simple chair, keeping your back erect if you can. The more traditional postures are the lotus position, sitting on a pillow with each foot upon the opposite thigh, and variations such as the half lotus (one foot on the opposite thigh, the other out in front of the opposite knee). This is difficult for many people. Some people kneel, sitting back on their legs or on a pillow between their legs. Many use a meditation bench: kneel, then place a little bench beneath your behind. But meditation is also done while standing, slowly walking, lying on the floor, or even in a recliner!

Traditionally, the hands are placed loosely, palms up, one on top of the other, and with the thumbs lightly touching. This is called the cosmic mudra, one of a large number of symbolic hand positions. You may prefer to lay them flat on your thighs, or any other way that you find comfortable.

Your head should be upright, but not rigid. The eyes may be closed, or focussed on a spot on the ground a couple of feet ahead of you, or looking down at your hands. If you find yourself getting sleepy, keep your eyes open!

Beginning meditators are often asked to count their breath, on the exhale, up to ten. Then you begin back at one. If you loose track, simply go back to one. Your breath should be slow and regular, but not forced or artificially controlled. Just breathe naturally and count.

A few weeks later, you may forego the counting and try to simply follow your breath. Concentrate on it entering you and exiting you. Best is to be aware as fully as possible of the entire process of breathing, but most people focus on one aspect or another: the sensation of coolness followed by warmth at the nostrils, or the rise and fall of the diaphragm. Many meditators suggest imagining the air entering and exiting a small hole an inch or two below your navel. Keeping your mind lower on the body tends to lead to deeper meditation. If you are sleepy, then focus higher, such as at the nostrils.

You will inevitably find yourself distracted by sounds around you and thoughts within. The way to handle them is to acknowledge them, but do not attach yourself to them. Do not get involved with them. Just let them be, let them go, and focus again on the breath. At first, it might be wise to scratch when you itch and wiggle when you get uncomfortable. Later, you will find that the same scant attention that you use for thoughts and sounds will work with physical feelings as well.

A more advanced form of meditation is shikantaza, or emptiness meditation. Here, you don't follow anything at all. There is no concentration -- only quiet mindfulness. You hold your mind as if you were ready for things to happen, but don't allow your mind to become attached to anything. Things -- sounds, smells, aches, thoughts, images -- just drift in and out, like clouds in a light breeze. This is my own favorite.

Many people have a hard time with their thoughts. We are so used to our hyperactive minds, that we barely notice the fact that they are usually roaring with activity. So, when we first sit and meditate, we are caught off guard by all the activity. So some people need to use a little imagination to help them meditate. For example, instead of counting or following your breath, you might prefer to imagine a peaceful scene, perhaps floating in a warm lagoon, until the noise of your mind quiets down.
