What Would Need to Be True
Evidence that authentic contemplative teachers and operative teachers use genuinely identical teaching techniques, with no detectable difference in the actual practices or teachings (meditation, study, service), only in the framing (liberation vs. permanent unfreedom).
Evidence from practitioners who experienced both liberation (authentic teacher) and control (operative teacher) using the same framework: what was the actual difference they perceived only in retrospect?
Evidence that the same teacher can facilitate genuine liberation in one person and operative control in another, suggesting facilitator intention is the variable.
Or evidence that system architecture (whether the system explicitly supports graduation) is determinative regardless of facilitator intention.
