Having arranged a pleasing seat, observing silence, and with the mind made one-pointed—facing either east or north—one should repeat the unsurpassed mantra, intent on Pati, the Lord who frees the paśu (bound soul) from the pāśa (bondage).
Suta Goswami (narrating Shiva-puja and japa-vidhi to the sages of Naimisharanya)
It gives the inner method of Linga-puja: establish an auspicious seat, keep mauna, concentrate the mind, and perform japa—turning external worship into inward communion with Pati (Shiva).
By calling the mantra “anuttama” (unsurpassed), it implies Shiva as the supreme Pati, approached through disciplined awareness that loosens pāśa (bondage) and elevates the paśu (individual soul).
Mantra-japa with yogic supports—āsana (steady seat), mauna (silence), ekāgratā (one-pointedness), and auspicious orientation (east or north)—a practical Pāśupata-style discipline.
