Adhyaya 8: Yogasthanas, Ashtanga Yoga, Pranayama-Siddhi, and Shiva-Dhyana leading to Samadhi
स्वाध्यायस्तु जपः प्रोक्तः प्रणवस्य त्रिधा स्मृतः वाचिकश्चाधमो मुख्य उपांशुश्चोत्तमोत्तमः
svādhyāyastu japaḥ proktaḥ praṇavasya tridhā smṛtaḥ vācikaścādhamo mukhya upāṃśuścottamottamaḥ
Svādhyāya is declared to be japa; and the japa of the Praṇava (Oṁ) is remembered as threefold. The spoken recitation (vācika) is the lowest; the mental recitation is the principal; and the whispered recitation (upāṁśu) is the best of the best.
Suta Goswami (narrating to the sages of Naimisharanya, conveying Shaiva discipline of Pranava-japa)
It prioritizes inner worship (antar-yajana) through Praṇava-japa, indicating that refined, subtle recitation supports Linga-upāsanā by turning the pashu (soul) inward toward Pati (Śiva).
By centering the Praṇava and valuing mental/whispered japa, the verse implies Śiva-tattva is approached most truly through subtle, interiorized awareness rather than merely external sound—moving from gross to subtle toward the Lord.
Praṇava-japa as svādhyāya, taught in three modes—vācika (aloud), upāṁśu (whispered), and mānasa (mental)—with emphasis on the subtler forms as superior for yogic concentration in a Pāśupata-oriented discipline.
