Srimad Bhagavat Gita commentary chapter 18 verse 27

 Chapter 18 verse 27               

“The performer is considered in the mode of passion when he or she craves the fruits of the work, is covetous, violent-natured, impure, and moved by joy and sorrow.” 

The doer of action is considered to be performing in the mode of passion when they focus verily on the fruits of the action, is driven by need to acquire things and conquer milestones in comparison to others, their approach to actions are not pure minded, sometimes violet natured and is easily swayed by bouts of joy and sorrow resulting from the result of the action. A lot of us in corporate world behave this way majority of the time. There is also societal, peer and inherent vasanas for this passion to flare up in everyday life. Passion at work is required in moderation to get this accomplished but it should be done with total lack of doer ship.
