1. In the Presentation and Acknowledgements, there was:
"the shamans and the indigenous psycholigsts"
The last word should probably be 'psychologists'.

2. In the last paragraph, "the holly kingdom" should probably be "the holy kingdom".

3. In the same sentence as 2 above, "are you a priests? are you a kings?" mixes plural and singular in odd ways. It could be plural: "are you priests? are you kings?", or singular: "are you a priest? are you a king?"

Thanks for this, I am really looking forward to future instalments!
