मन्त्रराजं सप्रणवं ध्यायेत्सोऽपि न पश्यति । इत्युक्ता सा तपोनिष्ठा तपश्चरितुमागता
mantrarājaṃ sapraṇavaṃ dhyāyetso'pi na paśyati | ityuktā sā taponiṣṭhā tapaścaritumāgatā
Даже если кто созерцает царя мантр вместе с Пранавою (Ом), одной лишь этим он не узрит цели. Так наставленная, она — стойкая в подвижничестве — отправилась совершать тапас.
Narrator within Brahma–Nārada dialogue (attribution by section context)
Scene: A teacher-figure instructs an ascetic woman; behind them, a symbolic praṇava and mantra appear, while the ascetic turns toward the path of austerity in the mountains.
Mantra and meditation must be supported by disciplined tapas and steadfast conduct to bear fruit.
The setting is within the Hāṭakeśvara-kṣetra Māhātmya section of the Nāgara-khaṇḍa.
Meditation on the mantrarāja with Praṇava is referenced, alongside the necessity of performing tapas.
