unspoken agreement. In the case of two preclears working on each other, each one assuming in his turn the auditor's role, a conditioncan arise where each prevents the other from contacting certain engrams.

Engaged upon clearing each other, working alternately as auditor, they avoid, unknowingly, but by reactivecomputation, the mutualperiod, thus leaving in place painfully emotional engrams. —Notes on the Lectures Glossary Final approval 26 March 1990
