The human brain is a treasure house of unlimited power. When man loses his peace of mind at a time of crisis, he loses the ability to use this powerful resource, i.e. his intelligence, in a positive way. Negative thinking is an obstacle to human development, while positive thinking is a life-giver, a stimulant of human capacities. Therefore, when an individual or a nation is able to maintain peace in every situation, infinite possibilities open up. This is when ‘minuses’ can be turned into ‘pluses’.
