Chenchu is one of those aboriginal tribes of India 75 out of the innumerable castes classes and tribes which are marked as Primitive Tribal groups. The Govt defines the PTGs as
Primitive Tribal Groups (PTGs) are Scheduled Tribes known for their declining or stagnant population, low levels of literacy, pre- agricultural technology, primarily belonging to the hunting and gathering stage, and extreme backwardness.
I will tell you a story. A story that tells you more about Chenchus, the Indeginous tribe of Nallamalla. It starts and ends in Nallamalla. Long long ago even before any one of us could remember there lived Thinna a boy in the Chenchu PENTA, (Penta is hamlet) near the abode of the present day Lord Balaji the Richest God on Earth, Tirupathi.He is the son of a tribal couple, Naga, and Dutta, in the village called Vudumuru in Pothappinad. They were childless for a long time. By the grace of Lord Subrahmanya, a son, Tinna, was born to them. He learnt archery from his father. There was a tribal hunter called Thinna in the forest. On his way in hunting he comes across a Shiva linga abandoned in the woods. Feeling sorry for it, he decides to take care of it and starts offering raw meat of the animals he hunted as food for the linga. Impressed with his devotion and innocence Shiva accepted the offering. This continued for a few days.
Then returned the Brahmin who actually was visiting the linga for offering his prayers once in a week to find all the scattered pieces of meat. The proud Brahmana blames and even goes to the extent of scolding Lord Shiva for accepting all this, without waiting for him. Lord Shiva then asks the Brahmin, who sat in protest, to comprehend the depths of Thinna’s devotion.
On the following day, to test Thinna’s devotion, Shiva makes one eye of the linga to bleed. The innocent Thinna tries to cure it with all the herbs of his knowledge. Having failed he ends up replacing it with one eye of his. But then the other starts bleeding. Thinna without a second thought opts to offer his second eye too. Pleased with his devotion he blessed Thinna with moksha and then onwards, Thinna was referred to as “Bhakta Kannappa”.
( NOTE : Kannu in Telugu mean Eye )
It is also said that this Thinna is none other than Arjuna of the Pandavas who was promised moksha by Shiva then.The tribal hero who sacrificed his eyes for the lord, Bhakta kannappa and later went on to become the greatest devotee of the LORD SHIVA, It flashes in to our minds he is a Chenchu. Now designated by the Govt as one of the most PRIMITIVE TRIBAL GROUPS IN INDIA. But why has such a tribe full of Hospitatlity & warmth reverted in to the PRIMITIVE AGES and PRACTICES. Thats what is the question ?
Chenchus have various techniques to keep themselves free from wants ofcourse the needs are to be satisfied. The chenchu preferably carries two small packets in his dress. One packet has a collection of ash (no not at time to suprise) and the tamarind (not necessarily all the time). So when a chenchu feel hungry he take sthis ash made out of ripe tamarind selected from a special variety of the species and then mixes with it the ripe tamarind / water (u c its the one which is widely available) and then they consume it which keeps them away from Hunger for a couple of days. Tastes really good with the Ripe Tamarind and not bad even with water.
