On the second
day, the Lord is taken around the streets of the temple
on the Chinna Seshavahanain the morning.
In the night, the deities are taken
to the Uyala Mandapam for the Unjal Seva. They are then
taken around the streets of Tirumala on the Hamsavahana.
Hamsa or swan means pure.
Hamsa is believed to have a high intellectual capability,
and can distinguish the good from the bad. In addition,
Hamsa is visually appearing. It is for these reasons
that Lord Brahma uses Hamsa not only as his vehicle,
but also to chant the Vedas (the Vedas are believed
to have emanated from the soul of Vishnu).
