This paper examines the spiritual significance of Miaoli for the Tai Ji Men movement and the enduring emotions associated with the loss of its sacred land. The mountainous region, known for its natural beauty, once included 50 interconnected plots owned by Tai Ji Men and intended to become a major spiritual center. These lands were confiscated, unsuccessfully auctioned, and ultimately nationalized in 2020. Nationalization became a central theme in Tai Ji Men's public communications, yet individual and collective ways of coping with the loss have been diverse. Using qualitative interviews with long‑standing and newer members, the paper analyzes how practitioners remember, interpret, and emotionally relate to the Miaoli land. These experiences are contextualized within Tai Ji Men's identity culture and compared with classical antiquity's temenoi, sacred groves dedicated to worship, sacrifice, and mystical experience. The paper seeks to map the variety of references to Miaoli as a lost sacred space and to offer insight into how spiritual communities negotiate memory, identity, and resilience when deprived of a place central to their religious imagination.
