Matsya Purana — The Sarasvata Vrata: Vow for Sweet Speech
*मनुरुवाच मधुरा भारती केन व्रतेन मधुसूदन तथैव जनसौभाग्यम् अतिविद्यासु कौशलम् //
*manuruvāca madhurā bhāratī kena vratena madhusūdana tathaiva janasaubhāgyam atividyāsu kauśalam //
Manu said: “O Madhusūdana, by what vow (vrata) does one attain sweet and pleasing speech? And likewise, how does one gain the favor of people and exceptional skill in many branches of learning?”
This verse does not discuss pralaya directly; it shifts the dialogue to dharma—specifically, which vratas produce refined speech, social goodwill, and mastery of knowledge.
A king or householder must cultivate truthful, pleasing speech and public trust; Manu’s question frames these as dharmic attainments supported by disciplined observances (vratas) that strengthen learning and reputation.
No architectural (vāstu) rule is stated here; the ritual significance is the emphasis on vrata as a formal religious discipline believed to generate eloquence, popularity, and scholarly competence.
