"When placed alongside the teachings of Swami Dhirendra Brahmachari and Maharaj Virsa Singh, it becomes strikingly apparent that at least in its earliest years, Yogi Bhajan's Kundalini yoga was not a distinct practice, but essentially a combination of yogic mechanics learned from the former and the Sikh-derived mantras ("Ik Ongkaar, Sat Naam, Sri Waheguru") and chanting from the latter", Deslippe writes.But Virsa Singh rejected Bhajan’s Kundalini yoga and stated that yoga was not a part of the Gobind Sadan spiritual path after failing to gain control over the American Sikhs followers.
