Matsya Purana — The Sarasvata Vrata: Vow for Sweet Speech
वेदाः शास्त्राणि सर्वाणि गीतनृत्यादिकं च यत् न विहीनं त्वया देवि तथा मे सन्तु सिद्धयः //
vedāḥ śāstrāṇi sarvāṇi gītanṛtyādikaṃ ca yat na vihīnaṃ tvayā devi tathā me santu siddhayaḥ //
May all the Vedas and every śāstra, and whatever pertains to song, dance, and the like—O Goddess—be granted to me through your grace without deficiency; and may my attainments (siddhi) be fulfilled accordingly.
This verse does not address pralaya directly; it focuses on the devotee’s request for complete knowledge—Vedas, śāstras, and arts—through the Goddess’s grace.
It supports the ideal that rulers and householders should cultivate śāstric learning and refined arts (gīta-nṛtya) as part of dharmic education, seeking competence without deficiency for right conduct and cultured governance.
No explicit Vāstu or temple-architecture rule appears here; ritually, it functions as a stotra-prayer seeking siddhi and vidyā—often recited to invoke divine blessing for learning and accomplishment.
