This mode of worship of Śiva’s earthen phallic image is the muttering of the names of Śiva. O excellent sages, it yields all cherished desires. Please listen to me. I shall explain it.
मृदाहरणसंघट्टप्रतिष्ठाह्वानमेव च । स्नपनं पूजनं चैव क्षमस्वेति विसर्जनम् ४८ ।
The eight names of Śiva viz:—Hara, Maheśvara, Śambhu, Śūlapāṇi, Pinākadhṛk, Śiva, Paśupati and Mahādeva shall be used respectively for the rites of bringing the clay, kneading, installation, invocation, ceremonial ablution, worship, craving the forbearance and ritualistic farewell.
ॐकारादिचतुर्थ्यंतैर्नमोन्तैर्नामभिः क्रमात् । कर्तव्या च क्रिया सर्वा भक्त्या परमया मुदा ४९ ।
Each of the names shall be prefixed with Oṃkāra. The name shall be used in the dative case and Namaḥ shall be added to them. The rites shall be performed respectively with great devotion and joy.
The Nyāsa rite shall be duly performed and the Aṅganyāsa of the two hands shall also be performed. The devotee shall perform meditation with the six-syllabled mantra—Om namaśśivāya.
