तेन यावत्कृता नैव पूजा वै शंकरस्य च । तावत्पूजा न कर्त्तव्या कृता चेन्न शुभापि सा
tena yāvatkṛtā naiva pūjā vai śaṃkarasya ca | tāvatpūjā na karttavyā kṛtā cenna śubhāpi sā
So long as the worship of Śaṅkara has not been duly performed in that manner, no other worship should be undertaken; and even if it is performed, it does not become auspicious.

Sthala Purana: Ritual-ethical injunction: auspiciousness (śubhatva) of any worship is contingent upon first completing Śaṅkara’s prescribed worship; other devatā rites without Śiva-priority are declared fruitless/inauspicious.
Significance: Teaches ritual precedence and śaraṇāgati: placing Śiva at the center is said to ‘activate’ auspiciousness in all other religious acts.
The verse teaches a Shaiva Siddhanta priority: when Shiva (Pati) is not worshipped as prescribed, other acts of worship lack the power to become truly śubha (spiritually fruitful). It emphasizes centering all religious life on devotion to Śaṅkara.
In the Kotirudra context—closely tied to Jyotirliṅga pilgrimage—this instruction supports the principle that Saguna Shiva worship (especially Liṅga-pūjā) is foundational; other devatā-pūjā should be approached as subordinate and harmonized through Shiva-bhakti.
The takeaway is to perform Shiva-pūjā first and properly—typically with Liṅga worship, Panchākṣarī japa ("Om Namaḥ Śivāya"), and Shaiva marks such as bhasma/tripuṇḍra—before undertaking other devotional rites, so the overall practice becomes auspicious.
