Siddha practitioner Dr Bhani once spoke in an assembly of Agathiyar devotees about how a hymn by these saints carry various meanings according to one's temperament and understanding. While in school, he was told by his class teacher, this was a song praising Lord Ganapathy, where we stand in front of Ganapathy Murthy, bring our hands together and offer him a prayer. Later when he was learning Siddha medicine under the tutelage of his Siddha teacher, he was told the intricacies of Siddha medicine were hidden in this song. Moving on later to meet his spiritual teacher Yogi Ramaih, the Yogi told him that this song was full of Gnanam or Wisdom. Imagine one song can reveal so many facets according to the seeker's standing and understanding!
