I read her book: A PY trilogy of divine love. She's undoubtedly one of the spiritual giants the presence of Yogananda attracted to America.
I've been particularly interested in the part with James Lynn, when she describes his fastidiously precise vegetarian regimen and healthy habits. But then, for unknown reasons, JL got a brain cancer. And Durga Mata, astoundingly, remarked to him that his meticulous habits had not been useful to avoid that illness. She must have been on the same level as James Lynn, or nearly so.
Of course, probably Lynn's sickness was of a particular karmic nature and evidently was needed to hurl him into the state of Siddha, a totally liberated soul.
It’s also true that my meticulous habits about staying away from even the foul smell of cooked dead animals did not help me in me avoid getting melanoma stage 4 with a prognosis of of life for only a couple more years. But there are certainly other factors than even karma that play into such conditions. Although I heard that James Lynn spent long hours in the sun meditating I have no idea why cancer was the cause of his transition. But I do know that exposing myself to the constant light of the sun was the cause of my brain cancer. I suppose all our bodies need some excuse to leave the shores of this life. Doctors claimed that Yogananda ‘died’ of a massive heart attack. It makes me laugh a bit. Because he told his closest devotees he would be leaving before it happened and gave a talk before he slumped over, into Maha Samadhi.
