'Avi'
is the general name of a clan, like Chera, Chola, etc. Becouse
they ruled small territories, they were called Velirs; as
they belonged to Vellala caste they were known as Velirs;
becouse of their philanthropic nature they came to be called
Velirs; as they aided the kings in battle they were known
as Velirs; Muruga too is called Vel. And instead of calling
their ruler merely as Velir, they called him as Nedu Vel
Avi. This place was once a big city. Nakkirar in jhis Tirumurugattrupadai
only in this Padaiveedu, describes in 18 lines about several
sages who worshipped here and about them, their thoughts
and feelings. Finally when he praises them as having bodies
without illness. We understand the medicinal nature of this
place and of the existence of Siddhars. he adds "Devars".
Moolavars and others from heaven come here and bow.
