This is precisely why I think it would be great to have a system where less experienced shamanists were able to perform soul work for more experienced shamanists (and also, vice versa, so that a less experienced shamanist can see what it's like being guided through the process by someone else, in person, or as a distance healing). It gives invaluable experience, and would also get word of mouth around.

Many shamans (that I've met) like knowing that they have someone else to refer a client to if they're full up/unable to help; and sometimes they're in positions where they don't know or trust anyone else to refer to.

If they'd had mutual soul-work experiences with others, of the same, higher, or less experience - even if the belief systems themselves sometimes differed - there would be a greater sense of community, and a higher profile given to soul healing, and a better ability to treat the clients by saying things like 'well, I don't have the focus on ancestors that you seem to require, but X and X do, and here are their contact details'.
