Dehānta (Cyavana) and Upapatti: Kāśyapa’s Questions and the Siddha’s Account of Death, Pain, and Karmic Re-embodiment
तथा यद्यद् भवेद् युक्त संनिपाते क्वचित् क्वचित् | तत्तन्मर्म विजानीहि शास्त्रदृष्ट हि तत् तथा
tathā yadyad bhaved yuktaṃ sannipāte kvacit kvacit | tattan marma vijānīhi śāstradṛṣṭa hi tat tathā ||
同样，无论何处何时，凡肢体于关节处相合之点，当知其各各皆为要害之处（marma）；因为诸论典所示之要害标相，正复如是。

Educational Q&A
A marma is identified by anatomical convergence: wherever limbs or bodily structures meet and are joined at a junction, that location should be understood as a vital, life-sensitive point, as affirmed by authoritative śāstric tradition.
A Siddha is instructing the listener in a technical, śāstra-based way—defining how to recognize marma points by observing bodily junctions, a knowledge relevant to disciplined conduct in combat and to understanding bodily vulnerability.
