Adhyaya 84: शिवव्रतकथनम्
Uma–Maheshvara Vrata, Shula-dana, and Month-wise Ekabhakta Vrata
पुष्यमासे तु वै शूलं प्रतिष्ठाप्य निवेदयेत् पूर्वोक्तमखिलं कृत्वा भवान्या सह मोदते
puṣyamāse tu vai śūlaṃ pratiṣṭhāpya nivedayet pūrvoktamakhilaṃ kṛtvā bhavānyā saha modate
In the month of Puṣya, one should duly install the trident (Śūla) and offer it in worship. Having fully performed all the rites previously enjoined, the Pati rejoices together with Bhavānī—revealing the auspicious union of Śiva and Śakti that grants grace to the bound paśu (soul).
Suta Goswami (narrating Shiva-puja and installation rites to the sages of Naimisharanya)
It prescribes a Puṣya-month observance where Śiva’s emblem, the Śūla (trident), is ritually installed and offered—completing prior puja-steps—so the worship culminates in Śiva’s pleased bestowal of grace.
Śiva is implied as Pati, the sovereign bestower of anugraha (grace), who rejoices with Bhavānī—signifying that liberation and auspiciousness arise through the inseparable Śiva-Śakti reality acting for the uplift of the paśu bound by pāśa.
A monthly vrata-style puja practice: pratiṣṭhā (installation) and nivedana (offering) of the trident as part of a complete, previously taught Śaiva worship sequence—supporting Pāśupata-oriented discipline through regular, time-marked observance.
