Thinking is optional

There is a profound idea that I was introduced to when I first began to meditate - we have the option of thinking, or not thinking, anytime we want to. Emotional suffering may start with an incident, but grows exponentially with our thoughts. Focus on your surroundings, your breathing, or different thoughts and visuals. Better yet, deal with whatever incident caused the thoughts in the first place. Mental control is a skill, and becomes easier with practice. Study meditation or yoga - learn methods of bringing yourself back to what is really happening right now in your direct vicinity.
