I asked him about Yogi Bhajan who teaches kundalini yoga and has a sizable following in the United States. “That fellow is no yogi-shogi”, scoffed Swami Dhirendra Brahmachari. “I warned him that he was doing wrong. I told him that the only thing that would save him from hell would be the accumulated goodness of his American disciples. It is people like this Bhajan Yogi and that Udupa chap with his rats who are giving people wrong ideas about yoga.’Source: Not a Nice Man to Know by Khushwant Singh

In the early days of 3HO, Yogi Bhajan claimed that his spiritual teachers were Swami Dhirendra Brahmachari and Maharaj Virsa Singh. As has been documented by Philip Deslippe in his 2012 academic paper, “From Maharaj to Mahan Tantric: The Construction of Yogi Bhajan’s Kundalini Yoga“, after a disastrous trip to India with his cult followers, Bhajan changed his story. This book by Khushwant Singh was published in the year 2000.
