Anything you can do to lessen suffering in your community and in the world is known in Buddhism as Right Action. When you go to the supermarket, you can make the choice whether to practice Right Action or not. There are items for sale that have been produced by children who have no chance to go to school. There are items that have been made with materials that can be harmful. We are part of the collective whole, and even these individual decisions about what to consume affect the collective consciousness.
