Ācāra-vidhi (Rules of Conduct) — Yudhiṣṭhira’s Inquiry and Bhīṣma’s Normative Catalogue
बस्तिमूलं गुदं चैव पावकं समुपाश्रित: । वहन्मूत्रं पुरीषं चाप्यपान: परिवर्तते,अपान वायु जठरानल, मूत्राशय और गुदाका आश्रय ले मल एवं मूत्रको निकालता हुआ ऊपरसे नीचेको घूमता रहता है
bastimūlaṃ gudaṃ caiva pāvakaṃ samupāśritaḥ | vahanmūtraṃ purīṣaṃ cāpyapānaḥ parivartate ||
婆罗陀婆阇说道：阿帕那之风（apāna-vāyu）依止于膀胱根部、肛门与消化之火所在之域，恒常向下运行；携带尿与粪，遂将其排出体外。此教诲强调：以自制之心、如实而不矫饰地认识身体机能，亦是自知与克己的一部分；由对具身处境的清明，扶持伦理之行。

Educational Q&A
The verse teaches a clear understanding of the apāna-vāyu as the vital force responsible for downward movement and elimination. Such knowledge supports self-mastery: recognizing the body’s processes without attachment helps cultivate restraint, purity, and steadiness in dharmic living.
In a didactic explanation, Bharadvāja describes how apāna operates in the body—taking support near the bladder-root, anus, and digestive fire, and moving downward to carry and expel urine and feces—within a broader Shānti Parva discussion on inner discipline and the constituents of embodied life.
