न तु तत्र शिवोस्मीति बुद्धिं कुर्याद्विचक्षणः । भुक्त्वाचम्य शिवं ध्यात्वा हृदये मूलमुच्चरेत्
na tu tatra śivosmīti buddhiṃ kuryādvicakṣaṇaḥ | bhuktvācamya śivaṃ dhyātvā hṛdaye mūlamuccaret
然而明辨之人于此不应生起“我即湿婆”的念头。食毕行阿遮摩那（ācamana）净口，观想湿婆，并于心中诵持根本真言（mūla-mantra）。

FAQs
It teaches disciplined humility in worship: rather than claiming identity with Śiva, the devotee should purify oneself, meditate on Śiva, and recite the root-mantra inwardly—aligning the soul with Pati through devotion and right practice.

Perform ācamana after eating, meditate on Śiva, and recite the “mūla-mantra” in the heart—commonly understood in Shaiva practice as the Panchākṣarī mantra, ‘Om Namaḥ Śivāya,’ done with inner concentration.
