Her first work is the Thiruppavai, In these verses, she describes her yearning to serve Lord Vishnu and achieve happiness not just in this lifetime, but for all eternity. She also describes the religious vows (Pavia) that she and her fellow cowherd girls will observe for this purpose. It is said that Thiruppavai is the nectar of Vedas and teaches philosophical values, moral values, ethical values, pure love, devotion, dedication, single-minded aim, virtues, and the ultimate goal of life.
The second work by Andal is the Nachiar Tirumozhi, a poem of 143 verses. “Thirumozhi” literally means “Sacred Sayings” in a Tamil poetic style and “Nachiar” means Goddess. Therefore, the title means “Sacred Sayings of the Goddess.” This poem fully reveals Andal’s intense longing for Vishnu, the Divine Beloved. Utilizing classical Tamil poetic conventions and interspersing stories from the Vedas and Puranas, Andal creates imagery that is possibly unparalleled in the whole gamut of Indian religious literature.
