Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
कर्णान्तकृष्टैर्विमलैः सुवर्णरजतोज्ज्वलैः शास्त्रार्थैः संशयप्राप्तान् यथार्थान्वै विकल्पितैः //
karṇāntakṛṣṭairvimalaiḥ suvarṇarajatojjvalaiḥ śāstrārthaiḥ saṃśayaprāptān yathārthānvai vikalpitaiḥ //
With pure scriptural meanings—bright as gold and silver, drawn right up to the ear—he correctly distinguished the true senses of the teachings that had become clouded by doubt.
This verse is not about Pralaya; it emphasizes a method of dharmic learning—hearing and discerning scriptural meaning—used to remove uncertainty in any topic the Purana teaches.
It underlines a core duty: decisions should be based on correctly understood śāstra. A king (or householder) must resolve doubts through careful listening and discrimination of true meaning rather than acting from confusion.
No specific Vāstu or ritual rule is stated, but it supports how technical disciplines (like temple architecture or rites) should be learned: by close listening and clear interpretation of authoritative śāstric terms.
