May a Siyum Be Held on Yom Tov, or Is That ‘Mixing One Joy With Another’?

This source-based Torah study examines the question: Does celebrating the completion of a tractate on Yom Tov conflict with the principle that one joy should not be mixed with another? The meeting of a Torah celebration and festival joy raises a practical question about how different forms of sacred rejoicing relate to one another. It traces the issue through the parasha and the classical discussion without turning the material into an individualized ruling. The canonical review status is preserved for any practical, halakhic, ethical or theological claims.
