Saanthamai povan Arunachala
Arunachala, to satisfy my insatiable hunger I came to you, instead I ended up being eaten by you! Once I am completely digested by you, I will be at peace.
Saappadu means food, experience. sa+antham = saantham where antham is end. Saantham is peace, tranquility. Ego that has an end becomes food for Arunachala who is Atma swaroopam (I-I), and is thus swallowed and becomes one with the Lord. This results in a state of peace. This offering of ‘me, I’ to God is called ‘losing the “I”ness’ and surrender by shastras.
