President of The Times Square Alliance, Tim Tompkins, explains why they organized the event in an interivew with The London Telegraph:
"It's about how do you stay sane in our busy, desire-driven lives. Here you are in the middle of Times Square, all this advertising telling you all the things you desperately need, this is a chance to take care of one's spirit and to practice staying serene in the midst of all the distractions of modern, busy, city life."
Thousands of New Yorkers participated in the event, called Mind Over Madness and led by a professional bikram yoga instructor. The yoga sessions went from 7:30am to 7:30pm on the summer solstice, a day that marks the start of summer and the longest day of the year.
