मुनिमोहशमनम्
Pāśupata-yoga, Siddhis, Puruṣa-darśana, Saṃsāra, and Prāṇa-Rudra Pañcāhutī
अपानाय द्वितीया च व्यानायेति तथा परा उदानाय चतुर्थी स्यात् समानायेति पञ्चमी
apānāya dvitīyā ca vyānāyeti tathā parā udānāya caturthī syāt samānāyeti pañcamī
The second formula is for Apāna; the next is for Vyāna. The fourth should be for Udāna, and the fifth for Samāna—thus the vital airs are invoked in order, establishing the body as a fit vessel for Śiva-worship.
Suta Goswami (narrating Shiva-puja/nyasa procedure to the sages of Naimisharanya)
It prescribes prāṇa-invocation (nyāsa) as a preparatory purification, making the practitioner’s body a consecrated field for Linga-puja so the rite is not merely external but inwardly established.
By ordering the vital airs to be ritually placed, it implies Śiva as Pati—the inner Lord who presides over prāṇa and mind—so the pashu (individual soul) approaches Him by loosening pasha (impurity and distraction) through yogic alignment.
Prāṇa-nyāsa using grammatical case-formulas (dvitīyā, caturthī, pañcamī) for Apāna, Vyāna, Udāna, and Samāna—integrating mantra, breath-awareness, and inner consecration aligned with Pāśupata-style discipline.
