Intuition is the innate ability in everyone to perceive truth directly - not by reason, logic, or analysis, but by a simple knowing from within. That is the very meaning of the word "intuition": to know, or understand from within - from one's own self, and from the heart of whatever one is trying to understand. Intuition is the inner ability to see behind the outer forms of things to their inner essence.
Whatever you experience outwardly, take it within yourself and say 'I'm happy because I'm happy. I'm happy because God is in my heart.'
Live more quietly. Live more seeking God's presence in your own heart.
I had always been very rational, but I'd always used reason in such a way as to convince myself that reasoning alone would not solve anything, really. Reasoning is theoretical. Until you feel with your heart, you don't know if a thing is true. I found that book was absolutely authentic. I absolutely knew it was the truth. My whole heart accepted it.
