Mantraśodhana, Dīkṣā-krama, Guru-Pādukā, Ajapā-Haṃsa, and Ṣaṭcakra-Kuṇḍalinī Sādhana
विष्णोरिति स्थले विप्र कार्य ऊहोऽन्यदैवते । ततः कुर्यात्सर्वसिद्ध्यै त्वजपाया निवेदनम् ॥ ७५ ॥
viṣṇoriti sthale vipra kārya ūho'nyadaivate | tataḥ kuryātsarvasiddhyai tvajapāyā nivedanam || 75 ||
Ô brāhmane, là où le rite est prescrit avec la formule « de Viṣṇu », s’il doit être appliqué à une autre divinité, qu’on fasse la substitution appropriée. Ensuite, pour obtenir toutes les siddhis, qu’on accomplisse le nivedana (offrande) à l’Ajapā : le japa non proféré, le courant subtil du mantra.
Narada (teaching in a Vedanga/ritual-technical context, addressed to a vipra)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches disciplined mantra-application: even when a formula is Viṣṇu-centered, one may adapt it correctly for other deities (ūha), and then seal the practice by dedicating it through Ajapā—inner, continuous japa—aimed at complete spiritual efficacy (sarva-siddhi).
Bhakti here is expressed as faithful, rule-based worship: honoring Viṣṇu-mantra authority while allowing reverent adaptation for other devatās, and culminating in inward devotion via Ajapā (subtle remembrance), not merely external recitation.
It highlights mantra-śāstra procedure—ūha (textual/mantric substitution) and correct nivedana (ritual dedication). This aligns with Vedanga-style technical precision in how mantras are applied across deities and rites.
