North American indigenous folk often connect and seek guidance from their ancestors, their "grandmothers" and "grandfathers." In this context, grandmother and grandfather are Spirit Guides and part of your Guide Network.

If you look up this quote, notice how Radin inserts his own interpretation into what appears to be a first-person account of connection to an ancestor. Radin's inserts the phrase "the medicine" into the direct quote, thus subtly changing the meaning of the words provided by Rave, and betraying his academic bias. Instead of a channel/connection to a Spirit Guide, as indicated by Rave, Radin discounts Rave's own interpretation, and reduces the effect to a biochemical process. https://archive.org/details/journalofreligio07worcuoft/page/8/mode/2up
