To anthropologists, however, religious traditions often hide community best-practices. The tradition of consuming “choddo shak" on bhoot chaturdashi is one such ritual. It probably developed to collectively fight infectious disease outbreaks that occur post-monsoon and in winter, to boost community resistance and wellbeing. According to Charaka Samhita, the ayurvedic compendium of second century BC, we must eat edible green herbs and weeds in the month of Kartika, because all the doors leading to the house of the god of death, Yama, open now. To anthropologists, however, it’s a festival to refuel strength and health. An ancient custom, that finds mention for the first time in 16th century by Sanskrit scholar of the Bengal region, Raghunandan Bhattacharya. Was it prevalent all over India? No one knows, although it continues unabated in eastern India, especially Bengal.
