Locust-Expelling Rite (驱蝗): The Field Nobody Feeds

The swarm comes like weather. The priest walks to the field's edge and plants the locust-dispelling talisman where the wall of wings is nearest — and where the talisman stands, the grain still stands. When the swarm is severe, the altar is raised and the full machinery goes to work: a memorial to the Jade Emperor, dispatches to the city god and the village god, and the generals of the Qingwei register called down from the thunder offices.

⚡ The Locust as a Visitation

In the old agricultural cosmology, a locust swarm was not a natural disaster — it was a visitation. A force with an origin, a route, and a purpose, moving across the fields the way a dispatched army moves. The tradition read it as an omen-bearing presence that could be petitioned against, dispatched against, and driven beyond the boundary. This is why the remedies are structured as command: the talisman plants a command in the field, and the liturgy dispatches a command through the celestial machinery. The locust is treated as a force that answers to a chain of authority, and the rite climbs that chain.

This cosmological framing is not incidental. It explains why the tradition reached for the same tools it used against malevolent spirits and hostile forces — because the locust, in this reading, was one. The Taoist talisman (符籙) was the primary instrument of command: a written warrant, sealed with the authority of the lineage's masters, planted at the point of contact between the human world and the invading force.

📜 The Classical Record

Locust-dispelling is an old office of the ritual tradition, transmitted in the thunder compendia and given a formal place in the Qingwei lineage's own registers. The Qingwei method for the work is preserved under the title of the thunder-office locust-dispelling register, which names the highest authorities of the lineage — the Qingwei ancestral lord and the orthodox masters including the founding teacher Zhang Daoling (張道陵) and the Lady Wei Huacun (魏華存) — as the presiding powers, with the thunder-office locust-dispelling envoy Wang Bin and his assembly as the executing generals. The register is the lineage's standing warrant for the work.

Across various editions of the Taoist canon, the locust-dispelling rite appears as a formal category of field-protection liturgy, distinct from general exorcism and from agricultural prayer. It has its own memorial format, its own talisman forms, and its own chain of celestial recipients — a specificity that reflects how seriously the tradition took the threat.

For those who work with protective talismans today, the disaster-dispelling talisman (消灾符) carries the same structural logic: a written command, sealed with lineage authority, placed at the point of contact between the protected space and the incoming force.

🔍 The Two Scales of the Working

The rite runs at two scales. For the ordinary swarm, the locust-dispelling talisman is planted in the field at the point where the swarm presses, and the grain within its compass is held. For the severe visitation, the altar is raised and the full liturgy unfolds: a memorial to the Jade Emperor and the lineage's masters reporting the invasion, dispatches to the city god, the village god, and the district's temples, and the dispatch of the thunder-office generals to drive the swarm across the boundary. The planted talisman holds the line; the liturgy moves the line.

This two-scale structure is characteristic of the Zhengyi (正一) tradition's approach to field-protection: the talisman is the first response, the altar rite is the escalation. The talisman works alone when the threat is contained; the full liturgy is reserved for the visitation that has already broken through.

✨ The Thunder-Office Frame

The appearance of the thunder-office machinery in the locust rite is the mark of the Song and later tradition. After the thunder rites came to dominate the tradition, no great field-working was complete without the thunder generals, and the locust — a force of the sky moving across the land — was a natural subject for the thunder offices. The Qingwei lineage's register gives the work its own general, its own envoy, and its own presiding masters, so that the locust is answered by a dedicated chain of command rather than a borrowed one.

The classical Taoist tradition holds that the thunder generals operate as a standing army of the celestial bureaucracy, available to be dispatched against any force that moves against the order of the fields and the villages. The locust, in this frame, is not a natural phenomenon to be endured — it is an incursion to be repelled.

🌀 Sectarian Differences

The Qingwei lineage's register is the most formally documented version of the locust-dispelling rite, but the practice was not exclusive to it. The Zhengyi tradition at Longhu Mountain maintained its own field-protection liturgies, and local traditions across the agricultural regions of China developed their own talisman forms and memorial formats. The Quanzhen (全真) tradition, oriented toward internal cultivation rather than ritual service, did not develop a comparable field-protection liturgy — the locust rite belongs to the liturgical service traditions, not the cultivation traditions.

🌾 Timing and the Agricultural Calendar

The locust rite was not performed on a fixed calendar date — it was performed in response to the swarm. But the tradition recognized that certain periods of the agricultural year were more vulnerable: the weeks between the grain's heading and the harvest, when the crop was at its most exposed and the loss of a field meant the loss of a year. The memorial format in the Daofa Huiyuan reflects this urgency: it is written as an emergency dispatch, not a scheduled petition.

🔬 The Modern Reassessment

Modern scholarship reads the locust rite against the history of a disaster that the old world could not manage by engineering alone. The talismans planted in fields, the memorials filed with the heavens, the generals dispatched across the boundary — all of it was the religious technology of a people defending their one food supply against a force that arrived from the sky. The rite's persistence records both the scale of the threat and the limits of the old response.

For the historian, the locust register is a document of what an agrarian society feared most, and of the machinery it built to answer that fear. For the practitioner, it is a record of how the tradition understood the relationship between the human world and the forces that moved through it — and of the tools it developed to hold that boundary. The same logic that drove farmers to plant talismans in threatened fields also drove merchants and households to seek wealth-gathering talismans (聚财符) for their storerooms: both are acts of placing a written command at the boundary between what is protected and what threatens it.

The wealth-gathering talisman carries the same structural authority as the locust-dispelling talisman — a lineage warrant placed at the threshold, commanding the forces of fortune to enter and the forces of loss to withdraw.
