Having thus recited the mantra, he remained there facing north; then, in the prescribed manner, he regulated the breath—beginning with the utterance of Praṇava (Oṁ).

Tattva Level: pashu
Shiva Form: Dakṣiṇāmūrti
It teaches that mantra-japa becomes spiritually potent when joined to discipline of posture, direction, and prāṇa—beginning with Praṇava—so the mind turns steadily toward Pati (Lord Shiva) rather than remaining scattered in pasha-bound tendencies.
The verse describes the inner method that supports outer worship: before (or alongside) Linga-upāsanā, the devotee steadies breath and begins japa with Om, making the mind fit to contemplate Shiva in a saguna form while being led toward the higher, transcendent reality.
Face north, recite the chosen Shiva-mantra, perform prāṇāyāma in a rule-based way, and commence japa with the utterance of Praṇava (Om) as the sanctifying prelude.
