Skanda Purana — Nagara Khanda, Shloka 35
एकैकं वा त्रयाणां वा एकमेवं निमंत्रयेत् । ब्राह्मणान्मातृपक्षे च एष एव विधिः स्मृतः
ekaikaṃ vā trayāṇāṃ vā ekamevaṃ nimaṃtrayet | brāhmaṇānmātṛpakṣe ca eṣa eva vidhiḥ smṛtaḥ
จะนิมนต์ทีละท่านก็ได้ หรือเชิญทั้งสามพร้อมกัน หรือเชิญเพียงพราหมณ์ท่านเดียวตามแบบนี้ก็ได้ สำหรับฝ่ายมารดา ก็ทรงจำว่าใช้วิธีเดียวกันนี้เป็นกฎ
Skanda (deduced from Nāgarakhaṇḍa Tīrthamāhātmya instructional discourse style)
Scene: A householder consults elders/śāstra, then invites either one Brāhmaṇa or three together; a parallel scene shows offerings intended for the maternal line, indicating inclusivity.
FAQs
Ritual sincerity and correct method matter more than display; even minimal arrangements, when done properly, uphold dharma for both paternal and maternal ancestors.
The broader context is tīrtha-śrāddha in Nāgarakhaṇḍa; this verse itself does not name a particular location.
Invitation may be done individually, collectively for three, or even for one Brāhmaṇa; the same method applies for the maternal line rites.
