Devotees, mostly tribals, from Telangana, Andhra Pradesh, Odisha, Chhattisgarh, Madhya Pradesh, Maharashtra, Karnataka and other states are attending the four-day biennial festival at in Eturangaram wildlife sanctuary.
The devotees, including women, were standing in long queues to offer jaggery to tribal goddesses Sammakka and Sarakka, also called as Saralamma.
Sammakka and Sarakka were legendary warriors from the Koya tribe who died while fighting against the Kakatiya empire over 800 years ago.
The unique rituals will begin Wednesday night with the customary arrival of Sarakka's image from Kannepally village which will be placed on a platform. The image idol covered in red cloth will be brought in a vessel laden with vermilion and turmeric powder.
The idols of Sarakkaa's father Pagidigidda Raju and husband Govinda Raju will be brought to Medaram.
Devotees were having holy dip in Jampanna Vagu, a tributary of Godavari river. Jampanna was the tribal warrior and the son of tribal Goddess Sammakka who was killed in a war with Kakatiya Army. The tribals believe that a dip in the stream washes off their sins.
