If you live in a negative environment, the environment can trigger these seeds. If you live in a positive environment, then the seeds of craving, violence, hate, and anger are not touched, not watered easily. So it is wise for you to choose a good environment that will prevent these negative seeds from being touched often. You should not allow other people around you to touch these seeds, and you should not allow yourself to water them. When you read an article full of violence or watch a violent television program or film, you turn on the seed of violence.
