Harbhajan Singh Khalsa (born Harbhajan Singh Puri) (August 26, 1929 – October 6, 2004), also known as Yogi Bhajan and Siri Singh Sahib to his followers, was an Indian-born American entrepreneur, yoga guru, and spiritual teacher. He introduced his version of Kundalini Yoga to the United States. He was the spiritual director of the 3HO (Healthy, Happy, Holy Organization) Foundation (and business ventures), with over 300 centers in 35 countries. Harbhajan Singh has been accused posthumously of sexual abuse by hundreds of his female followers; an investigation called the Olive Branch Report found the allegations most likely true. Biography Early life Harbhajan Singh Khalsa was born on August 26, 1929 into a Sikh family in Kot Harkarn, Gujranwala district, in the province of Punjab (now in Pakistan). His father, Dr. Kartar Singh Puri, served the British Raj as a medical doctor. His mother was named Harkrishan Kaur. His father was raised in the Sikh tradition and young Harbhajan was educated in a Catholic school run by nuns. Singh learned the fundamentals of Sikhism from his paternal grandfather, Sant Bhai Fateh Singh. Theirs was a well-to-do landlord family, owning most of their village in the foothills of the Himalayas. Khalsa's schooling was interrupted in 1947 by the violent partition of India, when he and his family fled to New Delhi as refugees. There, Harbhajan Singh attended Camp College – a hastily put together arrangement for thousands of refugee students – and was an active member of the Sikh Students Federation in Delhi. Four years later, he graduated with a master's degree in economics. In 1953, Harbhajan Singh entered the service of the Government of India. He served in the Revenue Department, where his duties took him all over India. Eventually, Harbhajan Singh was promoted to a customs inspector at Delhi airport. In his final years in India, he also learned from Baba Virsa Singh at Gobind Sadan Institute. Coming west In 1968, Harbhajan Singh emigrated to Toronto, Canada equipped with an endorsement from that country's High Commissioner to India, James George, who was also a student of his. Harbhajan Singh made a considerable impact in the predominantly Anglo-Saxon metropolis. In three months, he established classes at several YMCAs, co-founded a yoga centre, was interviewed for national press and television, and helped set in motion the creation of eastern Canada's first Sikh temple in time for Guru Nanak's five hundredth birthday the
