पार्थिवप्रतिमापूजाविधानम्
Pārthiva-pratimā Pūjā-vidhāna — Procedure for Worship of an Earthen Icon
शिवस्य यजनं ज्ञेयं भोगमोक्षप्रदं नृणाम् । वारादिदेवयजनं कार्तिके हि विशिष्यते
śivasya yajanaṃ jñeyaṃ bhogamokṣapradaṃ nṛṇām | vārādidevayajanaṃ kārtike hi viśiṣyate
Know that the worship of Śiva bestows upon human beings both worldly enjoyment and liberation. Indeed, in the month of Kārttika, the worship of Śiva and the other deities becomes especially efficacious.
Suta Goswami (narrating Shiva Purana teachings to the sages at Naimisharanya)
Tattva Level: pati
Shiva Form: Mahādeva
It teaches that Śiva-worship is uniquely complete: it can grant rightful worldly fulfillment (bhoga) while also leading the devotee toward liberation (mokṣa), showing Śiva as both the giver of grace in life and the liberator beyond it.
In the Vidyeśvara/Viśveśvara context, Śiva is approached through worship (yajana), classically including Liṅga-pūjā as Saguna devotion; through that accessible form, the devotee receives fruits culminating in mokṣa by Śiva’s grace.
It implies performing Śiva-pūjā especially in Kārttika—daily offerings (water, bilva, lamps), japa of the Pañcākṣarī (Om Namaḥ Śivāya), and devotional observances—since worship done in this period is said to become particularly fruitful.
