Sarvodaya is a new thought that avws indivisible unity of life. It refuses to divide life into watertight compartments like individual versus society, society vs. State, secular vs. Religious etc. What is good for the individual is good for the society. There is no real conflict of interests.
Progress means progress of all.
One man's loss cannot become another man's gain. We create an illusion of a personal or private existence but all existence is one. The idea of sarvodya as preached by the Gita is to merge oneself in the good of all. This demands an absolute faith in truth and non violence. Never should people resort to untruth in their private and public life.
