Shloka 38
Prāyaścitta and Contextual Non-Culpability (प्रायश्चित्त-निमित्त-अदोषवाद)
अह:ःसु सततं तिष्ठेदभ्याकाशं निशां स्वपन् । त्रिरह्नि त्रिर्निशायां च सवासा जलमाविशेत्
ahaḥsu satataṁ tiṣṭhed abhyākāśaṁ niśāṁ svapan | trir ahni trir niśāyāṁ ca savāsā jalam āviśet ||
毗耶娑说：“令其白昼恒常站立，夜间在露天之下而眠。昼三次、夜三次，身着衣服亦当入水（沐浴）。”在此戒行的伦理框架中，这是严厉的自律与仪式净化；据说，受此誓戒的两次生者能从因无明而作的罪过中解脱。

Educational Q&A
The verse teaches rigorous self-restraint and bodily discipline as a form of expiation and purification: sustained endurance (standing by day), simplicity (sleeping under the open sky), and repeated ritual bathing are presented as means to cleanse faults—especially those arising from ignorance—when undertaken as a formal vow.
Within Śānti Parva’s instruction on dharma and remedial practices, Vyāsa prescribes a specific austerity-based observance (vrata/prāyaścitta), detailing its daily regimen (posture, sleeping conditions, and frequency of bathing) as part of guidance on how a dvija may atone for unintended wrongdoing.
