The word “Aru” in Tamil means pathway. The noun “padai” is derived from the verb form “padu,” which denotes directing or guiding. When ‘Aru' and ‘Padai' are joined together to form “Atruppadai,” it gives the meaning of providing guidance or directing towards the ultimate goal.

A devotee of Muruga who has already benefited from His grace may wish to provide guidance to another eligible devotee in the path of spirituality so that he may also reach the abode of Muruga. It is this process that is the central theme of “Thirumurugatruppdai.”

Thirumurugatrupadai is divided into six chapters. In due course of time, these have been taken to identify the six holy shrines of Muruga, namely Thirupparangundram, Thiruchendur, Thiruaavinangudi, Thiruveragam, Kundruthoradal, and Pazhamudhircholai. And the word Atruppadai Veedu was changed to “Arupadai Veedu” in due course. Also, the word Padai veedu also denotes “capital region,” so it may also be taken to mean the capital regions of Lord Muruga, who reigns supreme.
