Touching the head, one should recite the mantra beginning with “brahmajajñānaṁ prathamam.” Then, touching the space between the eyebrows, one should recite the Rudra-sūkta.
Suta Goswami (narrating Shaiva ritual procedure as taught in the Kailasa Samhita context)
Tattva Level: pashu
Shiva Form: Rudra
Mantra: ब्रह्मजज्ञानं प्रथमम् … (इति मन्त्रेण) … रुद्रसूक्तम्
Type: rudram
It teaches mantra-nyāsa: sanctifying the body by placing sacred sound on key centers (head and the ājñā region), aligning the devotee’s awareness with Rudra, the Lord (Pati) who grants purification and liberation.
Nyāsa and Rudra-sūkta japa prepare the worshipper’s body-mind as a fit vessel for Saguna Shiva worship (including Liṅga-pūjā), so that external worship is supported by internal consecration through mantra.
Perform mantra-japa while touching (nyāsa) the head and then the space between the eyebrows, reciting the quoted mantra and then the Rudra-sūkta—linking japa with focused awareness at the ājñā center.
