he lights dim to a fuzzy glow. Men and women, their bodies silhouetted in shad- ow, sit cross-legged on the floor without mov- ing. "Begin to observe your respi- ration," says Jonathan Kest, yoga instructor. "Strive for a natural, normal breath. Bare breath. Pure breath. The breath is strongly related to your state of health. Your state of bal- ance." Mr. Kest, a 27-year-old Uni- versity of Michigan graduate, operates the Center for Yoga, Relaxation and Health in Southfield. His class- es, held five days a week, attract men and women of different ages with different goals. Some come to supplement their aerobics or weight- lifting routines. Others attend to rehabilitate a bad back or injured limbs. Members of his class Left: A yoga student "finds her edge" without losing balance.

Can you feel your lungs expanding? Good. Awareness is the first step here ... Whenever you calm the mind down, reali- ty begins to surface, pleasant or unpleasant." Mr. Kest speaks rhythmical- ly, in modulated, soothing sen- tences. The hushed room, located on the second floor of a quiet of- fice building, is carpeted and warm. Piano music plays softly from a tape recorder. Members of the yoga class close their eyes. They stand feet spread, shoulder-width apart. They raise their arms slightly and turn their wrists outward. Their palms face blankly to the front. "This is a very vulnerable po- sition," Mr. Kest tells them. "But for change for the better to take place, you must be open. Vul- nerability is a source of strength "Find your edge," Mr. Kest says. "The only yardstick of suc- cess in this class is how long you can remain calm and relaxed." He tells his students that yoga is not about twisting and con- torting into a human pretzel. It's not about gymnastics. The pur- pose, he says, is to find balance in difficult poses that might seem easy at first. But when a yoga "Your body is like a garden." —Jonathan Kest pose is held over several minutes, it can create tension and pain. Relax into that pain, Mr. Kest says. Let go of the tension. Along with building strength, the ex- ercises help people develop pa- tience and calm that carries over into their everyday lives. Bloomfield Hills resident Car- ol Rohtbart began attending Mr. Kest's classes about four months ago. The devoted jogger wanted to supplement her rou- tine with something that would enhance coordination and reduce tension. Yoga has done both, she says. Since starting Mr. Kest's class, Ms. Rohtbart has taken classes during a vacation at an out-of- state resort. Nothing measures up to Mr. Kest, she says. "Jonny has a way of taking me through a dif- ficult pose. I can relax into the pain and stretch through it so the pain goes away. There's just something about his voice and energy level," she says. "He's inspir- ing:, In some ways, yoga rests on a principle sim- ilar to the halachic (Jew- ish law) mandate of maintaining one's health. "Your body is like a garden," Mr. Kest tells people suffering from neurolog- his class. "If you don't take time ical disorders, like multiple scle- to care for and cultivate it, all you rosis.

They lift a leg, rurming one foot up the inside of the calf of the other leg. Yoga dates back 6,000 years to India, where Hindu mystics preached that human beings could connect with their person- al deities through meditation, as- ceticism and certain postures. In the West, most yoga is taught as a mental and physical exercise, without reference to specific spir- itual beliefs. In the rush-hour decade of fax- es and car phones, Mr. Kest be- lieves yoga is gaining popularity. In Los Angeles, where his broth- er, Bryan, is an instructor, yoga classes have become more wide- spread than aerobics, he says. Of late, physicians have pre- scribed yoga for heart. disease and cancer patients, as well as s
