叢原火
そうげんび
壬生寺の悪僧が燃える怨火・叢原火
When viewed as a phantom fire born from the sacred lamps of Mibu-dera, the terror of Sogenbi lies not in the "breaking out of fire," but in the sharpness of karma where the one who stole religious fire is transformed into fire itself. Temple lamps illuminate the front of the Buddha and are the light that supports the dead and the faithful. The act of stealing that oil and offerings for selfish desire is spoken of not merely as stealing objects, but as the sin of snatching light from a place of prayer. Sogenbi is the form of that stolen light reversing itself, drifting through the night while burning the monk's face. The strength of Sekien's illustration is that it does not leave the fireball as an anonymous anomaly. The Sogenbi of "Gazu Hyakki Yagyo", by placing a face in the flames, forces the viewer to ask, "Whose fire is this?" It is not a distant light like Kitsunebi (foxfire) or Shiranui; rather, the visage of the sinner is trapped within the flames. Thus, Sogenbi is closer to a vengeful spirit than a natural phenomenon phantom fire, and simultaneously a ghost that cannot completely lose its human face. The location of Mibu-dera is also an important axis supporting this apparition. While the extant Mibu-dera is famous for the Shinsengumi and Mibu Kyogen, in the context of Sogenbi, the Jizo-do, sacred lamps, and temple discipline come to the fore. Unlike fires drifting deep in the mountains or over the sea, Sogenbi is a fire born from the internal ethics of a temple, and can be read as the figure of one who betrayed the community's faith and is now unable to leave the temple's vicinity. This is precisely why Mibu-dera is recorded as its true name, rather than roughly setting its location just as "Kyoto Prefecture." If we draw connections, Sogenbi extends in three directions: Kazenbo, Ubagabi, and Onryo (vengeful spirits). It is close to Kazenbo in being "the spirit fire of a Kyoto monk," and resonates with Ubagabi in that "a sin concerning oil and sacred lamps becomes fire." It shares a broad framework with Onryo, where the unpurified emotions of the dead remain as disasters or anomalies. Placing Sogenbi in the center of this triangle, it rises not as a mere flame yokai, but as a miniature Kyoto ghost story tying together a temple, a sin, and punishment after death.
