Yeah, Ayurveda. I have nothing against natural medicine. My great, great grandmother was full-blooded Oglala Sioux, and they knew a thing or two about healing with plants and the four winds (and hallucinogenics). Problem is, they couldn't cure or fix everything, and again, something like lukemia isn't fixed by a plaster or a tea. The Sioux certainly died en masse thanks to Europeans, and those who are left continue to die, as do Ayurvedic practicing Indians and everyone else, regardless of the medicine they believe in.
Then again, plains Indians like the Oglala probably didn't get lukemia, as they weren't exposed to the carcinogens that we are today. So, for what they had to deal with, their healers were pretty effective. But ask any doctor, Ayurvedic, medicine man or PhD, and if they are being honest they will tell you that when people become ill they either get better or they don't, and they (the healers) have very little to do with the outcome. They are there to make the patient feel better.
Not really the topic anyway, I think the real issue is Bukowski was scared, as I suppose most of us will be when we're near the end, and he was up to try anything.
He mocked and ridiculed Linda's beliefs repeatedly, for years and years, so there is no reason to believe that he suddenly saw the light and embraced meditation or anything else that he tried out of desperation. When Linda describes him meditating, she is projecting her own transcendent feelings onto him. But she doesn't really know what he was thinking as he sat there.
