Yogi Bhajan
Yogi Bhajan, also known as Siri Singh Sahib to his followers, was an American entrepreneur, yoga guru, and putative spiritual teacher. He introduced his version of Kundalini yoga to the United States. He was the spiritual director of the 3HO foundation, with over 300 centers in 35 countries. He was accused of sexual abuse by several dozen of his female followers; an investigation called the Olive Branch Report found the allegations most likely true.
