In terms of psychological health, if you are inclined toward yoga or meditation, the following analogy may help: meditation is the craft of sitting, and yoga is the craft of movement. Meditation uses sitting as the focus. Yoga uses physical movement as the focus. In each case, the act of doing serves as a way to occupy the body and mind. During each session, the practitioner experiments with his boundaries and learns to respect them.
