Adhyaya 70: आदिसर्गः—महत्-अहङ्कार-तन्मात्रा-भूतसृष्टिः, ब्रह्माण्डावरणम्, प्रजासर्गः, त्रिमूर्ति-शैवाधिष्ठानम्
मुख्यसर्गं तथाभूतं दृष्ट्वा ब्रह्मा ह्यसाधकम् अप्रसन्नमनाः सो ऽथ ततो ऽन्यं सो ह्यमन्यत
mukhyasargaṃ tathābhūtaṃ dṛṣṭvā brahmā hyasādhakam aprasannamanāḥ so 'tha tato 'nyaṃ so hyamanyata
梵天见那初生之造化虽如是成就,却不能达其所用,内心不悦;因此他转念另起一途而行创造。
Suta (narrating Brahma’s action within the creation account)
It shows that creation is not merely mechanical; when it fails to serve its higher aim, Brahmā seeks a different means—implying that true fulfillment of srishti ultimately aligns with Pati (Shiva) and the conditions for the soul’s (pashu’s) uplift, which Linga worship later embodies.
Indirectly: the inadequacy of the ‘primary creation’ hints that without orientation to Pati (the supreme Lord, later revealed as Shiva), creation cannot become ‘sādhaka’—effective for removing pasha (bondage) and guiding pashus toward liberation.
No specific puja-vidhi is stated; the takeaway is preparatory—creation must be re-ordered so that disciplines like Pashupata Yoga and Shiva-upasana (centered on the Linga) can become possible and spiritually effective.
