There is one ceremony or the other almost daily for Lord Venkateswara manifest on Tirumala.
Different ceremonies are conducted on a grand scale for the Lord with different time frames— daily, fortnightly, monthly and yearly. Of them, special mention may be made of annual Brahmotsavas.
Devotees go on raptures witnessing the Lord on different carriages and earnestly wait for the next earliest opportunity to visit them. Brahmotsavas are conducted twice this year much to their jubilation.
Because of the addition of one month as per the Telugu Calendar, two categories of Brahmotsavas are conducted this year, namely—Salakatla and Navaratri (nine-day).
Lord of Seven Hills on Lion-Carriage – Simha Vahana Seva
The Lord appears on the Lion carriage (Simha Vahana Seva) on the third day morning of Brahmotsavas. Manifesting Himself as the lion, He suggests eradication of violence in human nature.
Just as the animals are scared at the sight of the lion, human beings should restrain themselves from sin for fear of punishment at the hands of the Lord. In yogic science, the lion is a symbol of forbearance and speed. Thus, the lion simile suits the Lord.
