Materials, Classes, and Fruits of Linga-Worship
शैलजं रत्नजं वापि धातुजं वापि दारुजम् मृन्मयं क्षणिकं त्यक्त्वा स्थापयेत्सकलं वपुः
śailajaṃ ratnajaṃ vāpi dhātujaṃ vāpi dārujam mṛnmayaṃ kṣaṇikaṃ tyaktvā sthāpayetsakalaṃ vapuḥ
Whether fashioned from stone, gemstones, metal, or wood, one should abandon the clay Liṅga—being perishable—and establish the complete, embodied form (sakala-vapuḥ) of the Lord for worship.
Suta Goswami (narrating Shiva’s Linga-sthapana injunctions within the Purva-Bhaga discourse)
It prioritizes durable materials (stone, gem, metal, wood) for Linga-sthapana and discourages a perishable clay Linga for long-term, established worship.
By mentioning “sakala-vapuḥ,” it points to Shiva as Pati who can be approached in a manifest, worship-supporting form, while still implying the deeper distinction of manifest (sakala) and transcendent (niṣkala) aspects.
It highlights Linga-sthapana (ritual installation) as the stable basis for daily puja—supporting disciplined practice that steadies the pashu (soul) toward Pati through regular observance.
