He Mo — The Ritual Communion with Ancestral Souls 合莫
Paul PengHe Mo (合莫, Hé Mò, lit. "Uniting with the Spirit Realm") is the ritual moment of communion between the living and the ancestral dead in Zhou sacrifice. The lord and his lady present offerings in alternation — a ritual dialogue designed to delight the souls (嘉魂魄) of the ancestors and draw them into communion with the living. Recorded in the Liji (礼记), "Liyun" (礼运) with commentaries by Zheng Xuan (郑玄) and Kong Yingda (孔颖达), He Mo represents the culminating moment of the ancestral sacrifice — when the boundary between the living and the spirit world is temporarily dissolved.
He Mo (合莫, Hé Mò, lit. "Uniting with the Spirit Realm") describes the ritual moment in Zhou ancestral sacrifice when the living and the dead achieve communion. The term combines 合 (hé, to unite) with 莫 (mò, the spirit realm). The term is recorded in the Liji (礼记, "Book of Rites"), "Liyun" (礼运) chapter, with authoritative commentaries by Zheng Xuan (郑玄) and Kong Yingda (孔颖达). He Mo represents the culmination of the ancestral sacrifice, following the initial offerings and preceding the feast — the moment when the boundary between the living and the spirit world was temporarily dissolved.
The Liji (礼记), "Liyun" (礼运) records:
"The lord and his lady make alternating offerings, to delight the soul and spirit — this is called He Mo."
Zheng Xuan (郑玄) and Kong Yingda (孔颖达) provide the authoritative interpretation of He Mo, explaining the ritual logic of the alternating offerings and the significance of the communion moment. The lord's offering and the lady's offering together create a complete ritual dialogue — the masculine and feminine principles of the living household united in addressing the ancestral spirits. This dual offering structure mirrors the complementary nature of the ancestral couple being honored.
In the Zhengyi tradition, He Mo finds its direct counterpart in the Taoist concept of ritual resonance (感应, gǎn yìng) — the moment when sincere ritual action bridges the human and divine realms. The Zhengyi liturgical canon teaches that properly performed ritual creates a channel (通, tōng) between the practitioner and the celestial realm, a principle first articulated in the classical He Mo communion. The priest's invocation, like the lord and lady's alternating offerings, is a structured dialogue with the divine — not a monologue but a conversation.
The history of Taoist fasting and offering rites traces how the He Mo's communion logic was absorbed into the Taoist liturgical framework. The Zhengyi school's emphasis on sincere intention (诚意) as the prerequisite for ritual efficacy is the direct descendant of the He Mo's requirement that the offerings genuinely delight the ancestral souls — ritual form without sincere intention produces no communion.
