A medicine man's secret handbook, maybe from Indochina / India? (exotic language)?

[mesinik]

Problems with "heavyweight" ciphertext, crypto theories: 

• this book seems kind of too smooth and fluent
  
• too long
  
• probably too old (or at least has a too plain, simple-minded look and feel).
  

So, could these stats somehow be possible in a text in a natural language?

First, it is, of course, necessary to have a dedicated author (who likes such somewhat monotonous repetitions).
One way for it might be a "medicine man", who either:

• wants to create a book about some "secret science", to get some fame... and it might create some "placebo effects" for his patients, too .. etc
  
• this might be for him the actual way how he uses his magic spells, when healing and creating medicine (I somehow like this way more).
