Thiruppavai

Tiruppavai consists of 30 verses and a verse is chanted on each day of Margali. Tiruppavai belongs to the Pavai genre of songs, a uniquely Tamil tradition sung in the context of the Pavai vow observed throughout the month of Maarkazi, originally by unmarried girls praying to the Pavai goddess (related to Parvati) for a blissful married life. Sri Vaishnavas sing these stanzas every day of the year in the temple as well as in their homes. This practice assumes special significance during Margazhi: each day of this month gets its name from one of the thirty verses. There are references to this vow in the late-sangam era Tamil musical anthology Paripadal.
Tamil Vaishnavas sing these songs to bring peace, prosperity and Divine Grace. Andal assumes the guise of a cowherd in these 30 verses. Andal appears intent upon performing a particular religious vow to marry the Lord, thereby obtain His everlasting company, and inviting all her girl-friends to join her. Towards the end we learn that she did not actually perform a religious rite; but is simply praying to be granted the service of the Lord for eternity. She yearns for everlasting happiness and service of the Lord.
