An excerpt from The Mind: Its Projections and Multiple Facets by Yogi Bhajan (page 13).
To win the game of life you must have caliber. To have caliber you must have an Applied Mind. An Applied Mind is a mind that processes everything positive and negative then acts from the Neutral Mind to express you. The Applied Mind uses the Neutral Mind to assess all positive and negative, but does not react on that basis. It acts to cause a cause that leads to the fulfillment of you and your destiny, you and your highest identity.
