# Terminology decisions for Tai Chi Mindfulness Ball 15-Minute Guided Practice

- 对跖点 / 对趾点 → "opposite sides of the ball" / "opposite points"
  - Base instruction used "opposite sides of the ball."
  - Source uses 对跖点 (geometric antipodal point) and 对趾点 interchangeably.
  - Decision: keep the base rendering "opposite sides of the ball" for the posture cue; use "opposite points" in the explanation of the meditation object to avoid repetition.

- 丹田 → "dantian"
  - MPI term DB only gives "pubic region; point two inches below the navel where one's qi resides."
  - Meditation-translation reference recommends keeping "dantian" as a well-known meditation/qigong term.
  - Base instruction used "lower abdomen"; source explicitly says 丹田, so "dantian" is used here.

- 无我 → "selfless" / "selflessly"
  - In this movement/mindfulness context the sense is "no separate controller imposing on the action" rather than the philosophical doctrine of non-self.
  - Decision: render as "selfless" (adjective) and "without controlling" to keep it practical and oral.

- 中道 → "Middle Way"
  - Standard rendering; used here in the physical sense of balanced effort (not too tight, not too loose).

- 随喜 → "rejoice in"
  - DoT preliminary/BAICKZ uses "rejoice."
  - Closing line "随喜大家练习正念球的功德！" → "Rejoice in the merit of everyone practicing the Tai Chi Mindfulness Ball!"

- 空掌拍打 → "using relaxed, open palms"
  - Base instruction rendering; reused.

- 闭合毛孔 → "seal in the warmth"
  - Base instruction rendered this concept interpretively as "preserve the warmth and energy."
  - Kept closer to the physical image while preserving the meaning: "Release tension in the muscles and seal in the warmth."

- 三个九十度 → "the three right angles of your body"
  - The source condenses the base posture description (thighs parallel, lower legs vertical, feet flat) into this phrase.
  - Rendered literally since the posture cue is familiar in Tai Chi/qigong instruction.

- 七支盘坐 → base instruction used "Seven-Point Posture of Vairochana"; source says 席地盘坐 (sit cross-legged on the floor/cushion), so not used here.
