पार्थिवप्रतिमापूजाविधानम्
Pārthiva-pratimā Pūjā-vidhāna — Procedure for Worship of an Earthen Icon
परभागस्तु देवानां दिवा युक्तः प्रशस्यते । उदयव्यापिनी ग्राह्या मध्याह्ने यदि सा तिथिः
parabhāgastu devānāṃ divā yuktaḥ praśasyate | udayavyāpinī grāhyā madhyāhne yadi sā tithiḥ
Đối với chư thiên, phần sau của thời phần, khi hòa hợp với ban ngày, được tán dương là cát tường. Nếu tithi kéo dài qua lúc mặt trời mọc thì nên thọ nhận tithi ấy; cũng vậy, nếu hiện hữu vào giữa trưa thì cũng được xem là hợp lệ cho nghi lễ.
Suta Goswami (narrating traditional ritual/time-determination rules to the sages of Naimisharanya)
Tattva Level: pashu
Shiva Form: Sadāśiva
Offering: dipa
It teaches that devotion must be joined with dharma—worship is strengthened when performed at the properly ascertained sacred time (tithi), aligning the devotee’s act with cosmic order.
Linga-puja and vrata observances are traditionally tied to tithi; this verse gives a practical rule—accept the tithi that persists at sunrise or is present at midday—so Saguna Shiva worship is performed at the ritually valid time.
It suggests careful tithi-selection for vrata/puja: prioritize the udayavyāpinī tithi (spanning sunrise) and also accept the tithi present at midday when scheduling worship, japa, and offerings.
