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).
Serpent Sesha’s Service to the Resident of Ananda Nilaya – Pedda Sesha Vahana Seva)
Seven-hooded Serpent Sesha’s service (Pedda Sesha Vahana Seva) to the Lord along with His consorts Sridevi and Bhudevi. Since the Lord is settled on Seshadri making Sesha His bed, Sesha’s carriage is preferred on the very first day of celebrations.
Adisesha serves the Lord variously in different postures as the habitation, bed, seat, shoes, upper garment, pillow, umbrella to shade from sun and shower, pedestal and servant. Hence, he is regarded as Sesha.
This procession suggests the rise of serpentine kundalini from mooladhara (primary consciousness) to Sahasrara (highest consciousness) in yoga.
