If I had to describe zazen in one word, it would be "exercise." On my hard cushion, I appreciate for the first time a systematic how-to approach to spiritual development that one does. Rather than ignoring the body or regarding it as a source of trouble, as in many forms of Western spirituality, Zen uses it. Like sports, this religion has clear rules, coaches, and equipment — a whole technology that helps people to become "addicted" to the activity and benefit from its unexpected side effects. Like working out, this spiritual practice unites body and mind, brings order to life, whispers that this too shall pass, and makes one feel good when it's over.
