On the morning of Day Two of the Karthigai Festival, Surya Perai is the
Vahana for the Lord. Surya is the representation of Fire (or Agni) and the
fourth element of the Panchabhutas. The essential character of Fire is to
generate heat and according to Hindu Mythology, Agni is one of the Eight
Guardians that guard our Universe (known as Asta-dik-palakas).
During each procession the panchamoorthies are seated on their
respective Vahana. The word “Vahana” denotes “that which carries, that which
pulls” and signifies the mount of the God. The mount represents a Divine
attribute associated with the God.
Arunachala is replete with mythology connected with the Surya, the Sun
God. To find out more about Surya’s connection with the Hill, go to this link.
