तदेनां पीडितां चेद्यः पतिर्भूत्वा न पालये । ततो यास्ये शास्त्रवादान्नरकांतं न संशयः
tadenāṃ pīḍitāṃ cedyaḥ patirbhūtvā na pālaye | tato yāsye śāstravādānnarakāṃtaṃ na saṃśayaḥ
若有人既为其夫,却在她受苦受难时不加护持,那么依诸经论(śāstra)之教,他必堕至地狱边际;此无疑也。
Lomaharṣaṇa (Sūta) (deduced for Māheśvara-khaṇḍa narrative frame)
Scene: A moral tableau: an afflicted woman seeking refuge; the husband either shielding her (ideal) or turning away (warning), with a shadowy naraka boundary implied in the background as consequence.
Neglect of protection and care within marriage is adharma and is portrayed as leading to severe karmic consequences.
No tīrtha is referenced; the verse is a dharma-śikṣā (ethical instruction).
None; it is a normative rule of conduct backed by śāstric authority.
