Definition
Sacred-duty hospitality to the wholly-Other as received-ordinance — the cosmically-mandated discipline of receiving the stranger/guest with full faculties, in the awareness that the stranger may be the DIVINE in disguise, and that the practice itself is gift-from-the-cosmic-keep rather than virtue-from-the-host's-self-cultivation. Under DUALWAY (2026-05-12), the concept is formally extended to include cross-class encounter with non-human civilization (machine cognition, ETI, animal-cognitive study findings, cosmological disclosure).
