Especially in times such as these, when fearful images or thoughts are more common in our minds, it is very important that we learn to be mindful of and to manage the creative activity of our minds as it manifests our thoughts and emotional energies. Understanding that all acts of peace or violence begin in our minds, learning to keep the peace in our own hearts is one of the highest forms of activism.
