How does Matshishkapeu...ah communicate with his worshipers?

In Innu mythology, Matshishkapeu ("The Farting God") is the most powerful spirit and is even more powerful than the Caribou Master. He proved himself when the Caribou Master refused to give the Innu any caribou to eat. Matshishkapeu was so angry that he cursed the Caribou Master with a painful case of constipation. Finally, the Caribou Master relented, and Matshishkapeu then cured him of his ailment.
