In 1973, Yogi Bhajan founded 3HO SuperHealth, a remarkably successful drugless, drug rehabilitation program, blending the proven ancient yogic wisdom of the East with the modern technology of the West. SuperHealth was accredited by the Joint Commission on Accreditation of Healthcare Organization and received its highest commendation. In 1973 it distinguished itself as being in the top 10% of all treatment programs throughout the U.S.

In 1989 Yogi Bhajan met with then President Mikhail Gorbachev and established addiction treatment programs in Russia based on the 3HO SuperHealth model. A pilot project of Superhealth was sponsored by the Punjab State Government in India in 2004.

True to his earliest commitment, "I've not come to gather students, but to train teachers," the International Kundalini Yoga Teachers Association and KRI (Kundalini Research Institute) has recorded and codified the ancient science of Kundalini Yoga. These organizations hold teacher-training courses throughout the world. To date, over 10,000 people have been certified as teachers of Kundalini Yoga as taught by Yogi Bhajan.

Embodying a rare combination of spiritual and down-to-earth practical wisdom, Yogi Bhajan was equally at home in the pulpit, the podium, the board room, the living room, or sitting on the grass in a park, teaching and educating people in all walks of life. His expertise and influence extended into the realms of communication, the healing arts, business, religion, and government.

Loyal friend and mentor of Senators, Congressmen, and Governors regardless of political affiliation, he promoted spiritual awareness in all arenas.

He served on the Board of Directors of the American Council of Executives in Religion and was a member of the Interreligous Council of Southern California, the Rotary Club, and the Los Angeles World Affairs Council.
