Scientific findings show that intuition determines our actions much more than we think. The more intuitive power someone has, the less selfish they behave. The less selfish one is, the more happiness one can experience. Surprisingly, happiness is thus a result of intuition. This connection has been independently developed by intuition masters and mystics of all cultures for thousands of years. Intuition can be learned, selfless action can be learned, and happiness, or at least a significant approach to happiness, is achievable here and now. However, intuition and happiness do not come for free. The development of stronger intuition is linked to the reduction of selfishness. This requires attention and perseverance. The intuitive path is not an easy one.
