The Vedas outlined the duties of each varna. These duties were called dharmas. The Aryans believed strongly in the importance of fulfilling their duties.
These duties depended both on the varna that an individual belonged to, as well as on their age. The duties outlined what jobs an individual could do, what jobs they should do, and what jobs they must do. Every aspect of social life and behavior was outlined for them based on their varna.
