sarveṣu mantra-vargeṣu śreṣṭhaṁ vaiṣṇavam ucyate |
gāṇapatyeṣu śaiveṣu śākta-saureṣv abhīṣṭadam ||
vaiṣṇaveṣv api mantreṣu rāma-mantrāḥ phalādhikāḥ |
gāṇapaty-ādi-mantrebhyaḥ koṭi-koṭi-guṇādhikāḥ ||
vinaiva dīkṣāṁ viprendra puraścaryāṁ vinaiva hi |
vinaiva nyāsa-vidhinā japa-mātreṇa siddhidāḥ ||

“Among all classes of mantras of Gāṇapatyas [i.e., worshippers of Gaṇeśa], Śaivas [i.e., worshippers of Śiva], Śāktas [i.e., worshippers of Śakti], and Sauras [i.e., worshippers of Sūrya], Vaiṣṇava [mantras] are said to be the best fulfillers of desires. O best of the brāhmaṇas, even among Vaiṣṇava mantras, Rāma-mantras have greater results, crores and crores of times greater, than the mantras of the Gāṇapatyas and others, and verily are bestowers of attainments (siddhis) just by means of chanting (japa) indeed without dīkṣā, indeed without puraścaryā, and indeed without the process of nyāsa.”
