Thirumozhis
The 143 pASurams are organized in 14 segments, each one called a tirumozhi. Thus, the first set of 10 pASurams – the first tirumozhi, is called “tai oru ti’ngaLum”, based on the first phrase of the first pASuram. Similarly, all the other tirumozhi-s are named based on the first few words of the first pASuram of that tirumozhi.
Each tirumozhi deals with one specific topic. For example, the 8th tirumozhi called “viNNIla melAppu” deals with kOdai telling her plight to the clouds and sending them as her messenger to gOvindan, who is stationed in tirumalai. The first tirumozhi starts with a plea by Andal to kAmadevan for his help in uniting her with her nAthan, emperumAn. The remaining tirumozhi-s are dedicated to different efforts by Andal to somehow speed up her union with perumAL. In the process, she goes through lots of impatient waiting, and finally in paTTi mEindOr kArERu tirumozhi, she is reunited with perumAL.
