On the first day of TTD Brahmotsavams, in the morning Bagaru Thirucchi Utsavam and Dwajarohanam are held. In 2017, First day of Navaratri Brahmotsavam date is September 23.
And in the evening, Lord Malayappa swamy (Utsava Murthi of Sri Venkateshwara Swamy) goes around four mada streets of Tirumala in ‘Pedda Sesha Vahanam’. The four streets around the temple are called mada streets in temple traditions.
It is a feast to the eyes of devotees to see Lord Srinivasa going in this vahanam (vehicle) with an image of ‘adisesha’ (snake god). Adisesha is the couch of Lord Sri Maha Vishnu. He is the most ardent devotee of Lord and follows Him in all His incarnations like Sri Rama, Sri Krishna etc.
