Our family god called Kuladheivam in Tamil, has a temple in our village called poɬliwoʃ,” said the 66-year-old Kurtaz Vasamalli, who lives in the Nilgiri hills near Ooty. “We believe that the divine power comes to our villages from the temple…there is no idol worship.”
The hills, which are renowned for tea and coffee plantations, are considered sacred by the Toda tribe, who have lived there for thousands of years. The pastoral community believes that their gods and goddesses lived among them once and became a part of the sacred landscape over time.

Subsequent Indian censuses have continued to map the country's linguistic landscape. The 1961 Census of India recorded 1,652 mother tongues, of which SPPEL has identified 117 endangered languages. By 2011, this diversity had expanded significantly, with the census recording 2,843 different mother tongues. After further linguistic analysis, 1,369 were classified as recognized languages that experts could properly identify, while 1,474 remained unclassified. The census grouped all mother tongues with more than 10,000 speakers under established language categories. Languages spoken by fewer than 10,000 people are considered endangered.
A UNESCO report, developed in collaboration with the Indira Gandhi National Centre for Arts under the Ministry of Culture, emphasizes the urgent need to protect India's tribal and indigenous languages. The report highlights that when a language disappears, it takes with it irreplaceable cultural heritage and traditional knowledge systems.
