Wasn't the movement led by Yogi Bhajan is similar to Guru Nanak's ?
Guru Nanak was born in 1469 and travelled the World spreading the message of Waheguru after 330 years in 1799 -1849 the Khalsa raj came in Punjab under Maharaja Ranjit Singh for 50 years.Similarly Yogi Bhajan was born in 1929 and travelled the World spreading the message of Guru Nanak and Kundlani Yoga and believed that there would be 960 million Khalsa which will bring Khalsa raj for 5000 years.
Indian Sikhs after the massacre in partition in 1947 and Sikh genocide in 1984 has damaged the psychology of Sikhs to such an extent that they can't think the way Yogi Bhajan believed.I know it is the prophecy of Guru Gobind Singh ji but the negativity has eaten up their faith.Yogi Bhajan's students can bring up that confidence and positivity in the minds of the Sikhs and the people of the World.
