The Exposition of the Dvādaśī Vow for the Twelve Months
Dvādaśī-vrata-nirṇaya and Mahā-dvādaśī Lakṣaṇas
यदा तु धवले पक्षे द्वादशी स्यान्मधान्विता । तदा प्रोक्ता जया नाम सर्वशत्रुविनाशिनी ॥ १०५ ॥
yadā tu dhavale pakṣe dvādaśī syānmadhānvitā | tadā proktā jayā nāma sarvaśatruvināśinī || 105 ||
But when, in the bright fortnight, the Dvādaśī (twelfth lunar day) occurs together with Madhu (the month of Caitra), that observance is declared to be called Jayā—destroyer of all enemies.

Vrata: Jayā (Dvādaśī observance)
Primary Rasa: shanta
Secondary Rasa: bhakti
It defines a specific sacred timing: when Dvādaśī in the bright fortnight coincides with the month Madhu (Caitra), the vrata is called Jayā and is praised for removing hostile forces and obstacles.
By highlighting a named Dvādaśī observance, it points to time-based devotional discipline—keeping a vrata on an auspicious tithi as a supportive practice for Vaiṣṇava devotion and spiritual protection.
It uses calendrical computation—tithi (Dvādaśī), pakṣa (śukla/bright fortnight), and māsa naming (Madhu/Caitra)—which aligns with Jyotiṣa (Vedāṅga astrology) for determining correct ritual timing.
