Mokṣopāya: Bhakti-rooted Jñāna and the Aṣṭāṅga Yoga of Viṣṇu-Meditation
विधाय ह्यक्षरश्रेण्यां तत्तदर्थविचारणम् । स जपोमानसः प्रोक्तो योगसिद्धिप्रदायकः ॥ ९५ ॥
vidhāya hyakṣaraśreṇyāṃ tattadarthavicāraṇam | sa japomānasaḥ prokto yogasiddhipradāyakaḥ || 95 ||
Kapag inayos sa isip ang sunod-sunod na pantig ng mantra at pinagninilayan ang kahulugan ng bawat isa, ito ang tinatawag na mānasa-japa (japa sa isipan); sinasabing nagkakaloob ito ng mga siddhi ng yoga.

It defines mānasa-japa as mantra repetition performed inwardly with attentive sequencing of syllables and contemplation of meaning, presenting it as a refined practice that leads to yogic accomplishment.
By insisting on artha-vicāra (reflection on meaning), it turns japa from mere sound into conscious remembrance—supporting steady, inward devotion and focused awareness of the deity addressed by the mantra.
It implicitly draws on Śikṣā (proper handling of akṣaras/syllables) and Vyākaraṇa/Nirukta-style attention to meaning, emphasizing correct structure and understanding in mantra practice.
