binnamai iruppom Arunachala
Arunachala! Azhagu and Sundaram, while they seem to be different words, they mean the same thing: beauty. Like that, while you and I may look to be different, in reality we are the same.
Azhagu, a Tamil word and Sundaram, a Sanskrit word, while they seem different on the surface, in truth their meaning is the same. Like our eyes which are two but what they see is the same single object.
In the first verse Bhagavan worships Arunachala, the source of Self, in this verse he references his parents who are the source of his physical form. (Kanakammal writes Bahagavan worships ‘Uyirukkku ammai appan’ in the first verse. Uyir is jiva, the life force within us all. Ammai appan means mother and father.) Bhagavan’s parents are Azhagammai and Sundaresa Iyer. Like this Arunachala, you and I mean the same indivisible thing.
Azhagu and Sunadaram refer to jiva and the Lord respectively. All the saints and mahaans of the world have remembered their parents at some point in their writings. Thiruvalluvar, (the Tamil poet who composed Thirukkural), in his first verse mentions them as aadhi and bhagavan (the verse is: agara mudhala ezhuthellam aadhi baghavan mudhattre ulagu).
