Amid the 500,000 people who pass through the center of Manhattan on their way to work, I took part in an outdoor yoga practice held in honor of the Summer Solstice. Against the cacophony of police sirens and taxi horns, the occasional rumble from the subway, the perplexed stares of commuters and the urban aroma of bus exhaust, four thousand of us stretched, lunged, twisted and saluted the sun. It was surreal - in an odd and wonderful way. The event was the 10th annual Solstice in Times Square." The yoga class I attended was the first of four that were held throughout the day and evening. The early-morning class was led by Drisana Carey, a lanky instructor who also works as a model for Athleta. A midday class was lead by Rajashree Choudhury, the wife of Bikram Choudhury – the founder of the standardized yoga practice that consists of 26 poses done in an environment heated to 105-degrees. Carey had great presence and even greater poise when the audio on her microphone frequently cut out. She understood that New Yorkers who get on their yoga mats are still New Yorkers. Carey reminded us to try to transcend the rush-and-bustle of Times Square - to be, as she put it, "guided by our breath and our hearts and not by our egos." The movements were designed to be accessible for yogis of all levels, but the workout was tough. The mental challenges, however, were far greater: How to get zen amid the chaos?
