Manifest–Unmanifest Discrimination and the Supreme Path of Withdrawal
श्रोत्रं त्वक्चक्षुषी जिद्ना प्राणं ज्ञानेन्द्रियाण्यथ । पादौ पायुरुपस्थश्न हस्तौ वाक्कर्मणी अपि
śrotraṃ tvak cakṣuṣī jihvā prāṇaṃ jñānendriyāṇy atha | pādau pāyur upasthaś ca hastau vāk karmaṇī api ||
毗湿摩以分类来说明人的机能：耳、皮肤、眼、舌，以及（此处亦将生命之气 prāṇa 计入）为知之器；足、肛门、生殖器、手与言语为行之器。此教法旨在奠定伦理的自我治理：明了诸根，方能持制、正行，并以纪律安住于生活。

Educational Q&A
The verse teaches discernment of human faculties by distinguishing the instruments of knowing (jñānendriyas) and doing (karmendriyas). This classification supports ethical discipline: when one understands how perception and action arise through these faculties, one can practice restraint and direct them toward dharma.
In Śānti Parva, Bhīṣma is instructing Yudhiṣṭhira on dharma and inner discipline. Here he pauses to enumerate the sense-faculties and action-faculties as part of a broader teaching on self-mastery and right conduct.
