Janpad definition
Janpad means group of people or community and ‘Dhwansa’ means demolition. Therefore Janpadodhwansa literally means demolition or destruction of people or community. There are four factors which are common and essential for every living being i.e. Vayu (air), Jala (water), Desha (land) and Kaala (season). Vitiation of these four common factors is the cause for Janpadodhwansa and those having features otherwise are said to be wholesome.[7] Foremost reason for Janpadodhwansa has been described as Adharma and the root cause of Adharma is said to be Prajnaparadha. The code of good conducts are said to be dharma. Adharma is an antonym to Dharma which denotes lack of morality, or unrighteousness in the people. Unethical and non-harmonious or discordant practices among communities and people come under Adharma. Similarly acharya sushrut explained epidemics as marak while discussing ritucharya (seasonal regimen). It can be understood in present context that wrong deeds performed by human beings from generation to generation like polluting air, water and soil may be the cause of spread of air, water or soil pollution related diseases and also for diseases caused by extreme weather changes due to global warming.
