Rishi always exists and their natural background radiation impacts our cellular networks/functions and are eternal human-nature symbiotic pioneers across the biosphere called Bharath.. ie. Earth. After centuries of suppression, there has been a resurgence of interest and recognition of the value of traditional knowledge which are nothing but ever lasting life sciences for humanity to prosper without harming the nature. We are not only knowing our true history now but will find growing on it since time immemorial - A mystery.
