There’s a new twist in a long-running sex scandal involving a Beverly Hills-based yoga guru. A sixth woman is suing Bikram Choudhury, the founder of Bikram yoga, over sexual assault allegations. Choudhury built an empire on his brand of hot yoga, which involves a 90-minute sequence of poses performed in 105-degree rooms. It has attracted celebrity followers and made Choudhury a millionaire. But, for the past two years, he’s been beset by accusations of sexual assault and rape from former students. Now Choudhury is facing a half dozen civil lawsuits. We hear about the cases, and how Choudhury built a lucrative cult of personality around an ancient practice.
