Various Indian Ancient text guided the people to lead a virtuous life. They contained rules, societal divisions (e.g. Varna or caste system), etc in order to maintain social order. Ashram system or rule divides the life of a person and corresponding duties according to age into a four fold division. The person must spend his life according to these four stages for satisfaction.
