The 7 Blunders of the World - Gandhi

Gandhi's "Seven Blunders of the World" That Lead to Violence
 

The Seven Blunders of the World is a list that Mahatma Gandhi gave to his grandson Arun Gandhi, written on a piece of paper, on their final day together, not too long before his assassination. In his final years, the elder Gandhi kept his grandson close at hand and set aside an hour every day to be alone with the boy.  

This list grew from Gandhi's search for the roots of violence. He called these acts of passive violence. Preventing these is the best way to prevent oneself or one's society from reaching a point of violence.
