The threefold activities that are the motivating force of all actions are itemised now. 1) Jnanam means knowledge of the activity. 2) Jneyam means knowing how the activity is to be accomplished. 3) Parijnata means the knower who performs the activity. These three activities are prerequisite and are the impetus which impels one to perform prescribed Vedic activities for the satisfaction of the Supreme Lord Krishna. Contrarily they are also the impetus to enact mundane activities for personal gratification. Among these three activities jneyam is comprised of three subdivisions and explained in context of the Vedas are: 1) karanam how the activity becomes reality such as by donations of wealth or materials. 2) karma or engagement in the act itself such as yagna or ritualistic propitiation. 3) karta the agent who performs the action or initiates the action to be performed.
