This quote by Martin Luther King Jr. brings to mind the yoga concept of Ahmisa, non-harming. When we truly practice non-harming we look at what violence takes place within our own minds. Our thoughts are very powerful, choose them wisely. When our thoughts are of a negative nature whether they be directed to our own selves or toward others, they create harm. We are all connected, so we are all affected.
