I feel like we may be bashing heads here a little, the key point I thought was relevant was cultural integration, using archaic language does not fall into those categories. 

The above quote could guide said person in helping the dying elder.  Even thought none of said peoples are Daoists, or even Chinese the wisdom of the passage resonates past physical barriers that we constantly throw up.

Tibetans never came up with Buddhism it was brought over from India, same as Christianity, it started in Jerusalem.  Just because water falls from the sky does not mean we all can't drink it. 

To make a relevant post to the OP, as I have grossly digressed, becoming a 'shaman' from a western background is IMO as ND just said like stealing 'culture from colonised indigenous peoples'.  Taking some of that knowledge and transforming it is not.  I have a friend whom likes to trip sit, he does not call himself a shaman nor tries to be one but likes serving other people, I believe this to be an appropriate integration.
