यज्ञोपवीती देवानां निवीती ऋषितर्पणम् प्राचीनावीती विप्रेन्द्र पितॄणां तर्पयेत् क्रमात्
yajñopavītī devānāṃ nivītī ṛṣitarpaṇam prācīnāvītī viprendra pitṝṇāṃ tarpayet kramāt
Wearing the sacred thread (yajñopavīta) in the upavīta manner, one should offer tarpaṇa to the Devas; wearing it in the nivīta manner, one should offer tarpaṇa to the Ṛṣis; and wearing it in the prācīnāvīta manner, O best of brāhmaṇas, one should in due order offer tarpaṇa to the Pitṛs.
Suta Goswami (narrating traditional ritual instructions within the Linga Purana)
It establishes ritual purity and right order (krama) for offerings—Deva, Ṛṣi, and Pitṛ—so that Shiva-puja and Linga-archana are performed on a properly consecrated foundation of dharma and gratitude to the cosmic, seer, and ancestral lineages.
Indirectly, it reflects Shiva as Pati—the Lord who upholds cosmic order—where correct rites align the pashu (individual soul) with ṛta/dharma, loosening pasha (bondage) through disciplined conduct that supports higher Shaiva worship.
The practice is tarpana (ritual libation) with specific yajñopavīta positions—upavīta for Devas, nivīta for Ṛṣis, and prācīnāvīta for Pitṛs—serving as preparatory karmic discipline that complements Shaiva puja and Pashupata-oriented inner purification.
