Query: just plain odd

Out of all the great stuff out there for doulas & midwives, this isn't one of them. It's just odd. So 70's. Natural childbirth should be "natural" - teaching white women to make noises like they are from the Indian culture is not natural. I recommend any of Ina Mae Gaskins works or Penny Simkins stuff leagues above this. I know some people will disagree - fine - to each her own.
