Intelligence, spiritual and natural, is the key to a successful life. Without the spiritual intelligence your natural intelligence will have no positive, eternal impact on your life. Most major conflicts in the world are spiritual in nature. With the proper spiritual intelligence a great deal of those conflicts could be avoided. Spiritual intelligence is ability of your spirit and natural intelligence is ability of your brain. As the title indicates the "how" and the "when" are critical in achieving optimum intelligence. Once a certain age has passed the best opportunity is lost and the child is the one who suffer the consequences. The adults bear the responsibility in providing the environment conducive to the development of intelligence in the young generations.
