Luopu Yuanan

Luopu Yuanan (洛浦元安, 834–898) is one of the few Tang Chan masters whom the lamp records and the *Línjì Lù* both describe as having trained under masters in two of the great Tang lineages: he is named first as an attendant of Linji Yixuan, and then, after Linji's death, as a student of Jiashan Shanhui who received his final transmission from the Yaoshan stream^[1]. The *Línjì Lù* preserves the often-cited episode in which Luopu, having presented his understanding, was struck by Linji and struck back; Linji laughed and acknowledged him — an exchange read by later commentators as one of the school's archetypal demonstrations of "host and guest" parity^[2].

After leaving Linji's community Luopu turned south to Jiashan, who reportedly required him to abandon his Linji-style posturing before accepting him; he settled at Mount Luopu (in modern Hunan), where his recorded sayings show a teacher comfortable using either the sharp confrontational style of Linji or the more probing dialogical method of Jiashan as the moment required^[3]. His line did not flourish past the next generation, but his career provides important evidence of the late-Tang traffic between the Hongzhou / Linji and Qingyuan / Yaoshan houses before they hardened into the canonical Five Houses.
