Anything you want to do can be done with a combination of motives that reflect the influence of the three qualities of nature. Actions can be performed purely for the sake of doing the right thing, or for selfish motives, or for inappropriate reasons. When you do something simply because it needs to be done, with no strings attached, and it is done under the right circumstances involving the right people it is a pure action. If you do something reluctantly or with the thought of gaining merit or getting something in return, it is an action that is motivated by the selfish desires of your ego and mind. Doing anything rudely or contemptuously at an improper time or place to the wrong person is performing an action from a state of ignorance or dullness. Strive to perform all your actions willingly for the benefit of everyone around you, without thought of reward or honor and you will not generate any negative karma going forward.
