Kandhar Anuboothi is a collection of songs sung by the great Tamil Saint Arunagirinathar. The collection of songs were sung during the period 1400-1500 AD. There are 51 songs including the kAppu (Requesting Lord Ganesha to give His blessings to sing a complete collection of songs). Each song is dedicated to Lord Muruga and most songs have a pattern of two lines praising Lord Muruga and the remaining two lines requesting the Lord to grant true wisdom to overcome Maya or what is commonly seen as the 'illusory nature of the world'.
Kandhar Anuboothi is a deeply philosophical and spiritual treatise from Saint Arunagirinathar with profound mystical import.
