Thiruppavai is a set of Tamil devotional religious hymns attributed to the female poet-saint Andal .She is Periyalvar's daughter. She was on complete fast, and bakthi for all the 30days ( 'Paavai nonbu') during the month of 'Margazhi' (Dhanurmaasam) and composed 30 religious hymns at the age of 5, to attain Lord Ranganatha Perumal. Thirupavai consists of thirty stanzas (paasurams). This is the fourth pasuram sung in Ragam Varali. In this pasuram ANDAL requests the rain god (Varuna) to rain all over the land so that the land can raise crops to feed humanity. She also elaborates the process of how rain occurs.
