Guarding knowledge is not a good way to understand. Understanding means to throw away your knowledge. You have to be able to transcend your knowledge the way people climb a ladder. If you are on the fifth step of a ladder and think that you are very high, there is no hope for you to climb to the sixth.
Nhat HanhRoot out the violence in your life, and learn to live compassionately and mindfully. Seek peace. When you have peace within, real peace with others is possible.
