Oleh itu, japa berbisik (upāṁśu) diisytiharkan seratus kali lebih utama, dan japa dalam batin (mānasa) seribu kali lebih utama—berbanding bacaan yang dibuat dengan bunyi yang jelas, dengan intonasi naik turun, serta kata dan suku kata yang dilafazkan terang.
Suta Goswami (narrating the teaching on japa within the Linga Purana discourse)
It prioritizes inner worship (antar-yāga) during Linga-pūjā: moving from audible recitation to whispered and finally mental japa, which is taught as far more fruitful for pleasing Pati (Shiva) and purifying the pashu (individual soul).
By valuing mānasa-japa most, it implies Shiva is approached most directly through inward, subtle awareness—beyond gross sound—supporting the Shaiva Siddhānta emphasis that Pati is realized when the mind becomes purified and one-pointed, loosening pasha (bondage).
A graded discipline of japa—vācika (audible), upāṁśu (whispered), and mānasa (mental)—with the yogic takeaway that mental repetition is the most potent for dhyāna, mantra-siddhi, and Pashupata-oriented inner restraint.
