Matsya Purana — Eclipse-Time Planetary Bath
परमां सिद्धिमाप्नोति पुनरावृत्तिदुर्लभाम् सूर्यग्रहे सूर्यनाम सदा मन्त्रेषु कीर्तयेत् //
paramāṃ siddhimāpnoti punarāvṛttidurlabhām sūryagrahe sūryanāma sadā mantreṣu kīrtayet //
He attains the supreme siddhi, rarely obtained and hard to fall back into worldly return through rebirth. Therefore, at the time of the Sun’s influence (Sūrya-graha), one should always utter the Sun’s name within one’s mantras.
This verse does not describe Pralaya directly; it teaches a soteriological point—reciting Sūrya’s name in mantra-practice leads to a supreme siddhi associated with freedom from repeated return (punarāvṛtti).
It frames a practical daily discipline: a householder (and by extension a king as exemplar) should integrate Sūrya-nāma into mantra-japa as a regular observance, seeking inner mastery and merit rather than only worldly success.
The significance is ritual rather than architectural: it prescribes mantra-usage—uttering the Sun’s name during mantra-recitation, especially at solar times/conditions (sūrya-graha), as a means to attain high spiritual fruition.
