What are examples of fields, professions or roles that affect change primarily through intuitive or "channeling" type methodologies? (See details)

Real world examples that you’ve experienced, heard about or know of. I’m thinking of things like acupuncture, various “healers” (shamans, perhaps), feng shui, creative visualization—anything that might influence individuals, environments or cultural spheres on a level other than conventional paths such as language, law, marketing, medicine, etc.

If you have detail to share, so much the better.
