Cloaking one's statements in mysterious impenetrable gibberish, instead of speaking clearly and plainly, is a classic device of oracles, shamans, gnostic seers, and other such shepherds in search of gullible sheep.
The trick is in getting your acolyte to mistake complexity and opacity as hallmarks of a secret knowledge. Then, once hooked, said acolyte can be exploited, perhaps indefinitely, as he strains and struggles to understand the secrets for himself. The more gibberish that the shepherd speaks, the more entranced the sheep becomes. Quite the parlor trick.
