i do know that my religion instructor at Western Michigan University claimed that it is a well known fact that Paramahansa Yogananda was a womanizer and had mistresses. i was not there with him so how do i know? However he definitely has changed my life for the better. Many people claim that Jesus and Mary Magdalene were lovers. Again how do i know? ; i was not there and even if he did it would not take away from my awe of who he was and what he did. i have a personal friend who acknowledged that Yogi Bajan had women as lovers but that did not seem to dent her believing he was a spiritual teacher.
It is a well known fact.... But where is the hard evidence? Is your former instructor reliable? Or did he speak from biased grapevine info?
I know everything about some alleged escapades by Yogananda, alleged lover of Tara Mata and father of a girl from her, alleged father of Ben Erskine, alleged owner of a personal harem in M. Washington, which made Brahmachari Nerode sue him at the LA court.
None of the above was proved though. Also, I would believe that Sri Yukteswar was not so much of a prophet had he missed the facts only because he was living in India.
Also, Yogananda would have been deserted by the likes of Daya Mata and Saint Lynn, who practice strict celibacy and would never have tolerated a guru with such weaknesses.
