Is bread itself a mitzvah or only a means, and what changes when the spiritual dimension is missing?

This Torah study examines the question: Is bread itself a mitzvah or only a means, and what changes when the spiritual dimension is missing? The canonical Hebrew discussion develops the issue through the weekly Torah portion and the sources cited there, preserving the distinctions, tensions and practical implications that belong to the source itself. This localized layer is designed for study and discovery; it does not add a new halakhic, medical, legal, historical or empirical ruling beyond the canonical Hebrew source.
