How did the Chola temples become hub of economic, social and cultural life?

Answer: The Chola temples were not merely places of worship. They often became nuclei of settlements, which grew around them. The Brahman priests imparted education in Sanskrit in these temples. Important meetings were sometimes held inside the temple complex. These were also centres of craft production. Fairs were organised during religious festivals. Temples gave employment to a large number of people including priests, garland makers, cooks, sweepers, musicians, dancers etc. So we can say, temples were not only places of worship; they were hub of economic, social and cultural life as well.
