They called him a Saturn teacher. Yogiji knew what each person needed for enlightenment and he gave it to you straight. If you didn’t like it, too bad. Once, a lady disagreed with him over something. I remember, it was about how she was raising her son. He didn’t bother arguing. He just punched her in the nose in front of all of us. He really did.  Once when I lived in LA I had witnessed Yogiji physically kick a depressed young man mercilessly around the large meditation area of the Guru Ram Das Ashram in LA while the boy just lay there helplessly. As far as I was concerned it was Yogiji’s way of imparting some spiritual lesson to him. One of Yogiji’s secretaries, Nirinjan Kaur, who witnessed the event, told me that he had done much worse to all of them and for me not to worry about it.
