मृताहर्यो न जानाति मानवो यदि वा क्वचित् । तेन कार्यममावास्यां श्राद्धं माघेऽथ मार्गके
mṛtāharyo na jānāti mānavo yadi vā kvacit | tena kāryamamāvāsyāṃ śrāddhaṃ māghe'tha mārgake
หากมนุษย์ไม่รู้แน่ชัดถึงวันมรณกรรม ไม่ว่าเมื่อใดก็ตาม ผู้นั้นพึงทำศราทธะในวันอมาวาสยา (วันเดือนดับ) ในเดือนมาฆะ หรือมิฉะนั้นในเดือนมารคศีรษะ
Śiva (continuing the instruction to Devī/Pārvatī) (deduced from immediate continuity with prior verse)
Tirtha: Prabhāsa-kṣetra
Type: kshetra
Listener: Devī/Pārvatī
Scene: A night-sky amāvāsyā scene at the coast: dark moonless horizon, a devotee performs śrāddha by lamp-light; a calendar strip highlights Māgha and Mārgaśīrṣa as chosen months.
Dharma provides compassionate alternatives: even when details are unknown, one can still honor ancestors through prescribed substitute timings.
The rule is transmitted within the Prabhāsakṣetra-māhātmya, linking correct Pitṛ observance with the sacred authority of Prabhāsa traditions.
If the death-day is unknown, perform śrāddha on Amāvāsyā, or in Māgha, or in Mārgaśīrṣa.
