How did the importance of indigenous relationships develop? What spiritual service is provided?
"indigenous" where? when?
This question is far too broad to be considered as it is written unless you have a particular indigenous population in mind -- and those occurred (or still occur) all over the world at different times and for different time spans.
You'll need to focus your question more if you expect to answer it.
Once you do answer it, please repost if you'd like someone here to comment on your ideas.
