Matsya Purana — The Sarasvata Vrata: Vow for Sweet Speech
लक्ष्मीर्मेधा धरा पुष्टिर् गौरी तुष्टिः प्रभा मतिः एताभिः पाहि चाष्टाभिस् तनुभिर्मां सरस्वति //
lakṣmīrmedhā dharā puṣṭir gaurī tuṣṭiḥ prabhā matiḥ etābhiḥ pāhi cāṣṭābhis tanubhirmāṃ sarasvati //
O Sarasvatī, protect me with these eight embodied forms: Lakṣmī (prosperity), Medhā (intelligence), Dharā (supporting power/earth), Puṣṭi (nourishment), Gaurī (radiant auspiciousness), Tuṣṭi (contentment), Prabhā (splendour), and Mati (right understanding).
This verse is not a Pralaya narrative; it is a devotional invocation asking Sarasvatī to protect the devotee through eight auspicious powers (intelligence, prosperity, nourishment, radiance, etc.).
It supports dharmic life indirectly: a king or householder is urged to cultivate medhā (clear intelligence), mati (sound judgment), tuṣṭi (contentment), and puṣṭi (well-being), which are essential for righteous governance, learning, and stable household prosperity.
Ritually, it functions as a stuti suitable for recitation before study, counsel, or ceremonies seeking auspiciousness; it does not state specific Vāstu or temple-building rules, but invokes divine qualities often sought at the start of rites.
