A question of prime importance.
The thought and the emotion are deeply linked together. The thought is felt at the level of the head, the top of the body, like a command center. The emotion is felt at the heart level, the center of the body, like an engine center. Together, they make up the consciousness. The "intelligence" driven with "power". In emotion their is a smaller part of thought, in thought there is a smaller part of emotion.
Like thought, but in a different manner, emotion is language. It is communicating to us. The higher consciousness communicate through emotion all the time. It is a barometer for one to measure the world. Love is not an emotion, but is being felt with the help of emotion when it comes. Like fear or joy. These are not emotions, these are felt with emotions when they comes. So one can be sensitive to the world and observe it with another kind of intelligence.
When one do not listen to his/her emotion, alienation grows. Integrity disappear. True happiness is hard to reach. It is like missing a part of your being.
It is the ability to feel/understand the outside world for it's true purpose. It is the fuel to sustain a thought to become reality. It is the source of inspiring thoughts that surpass the thinker.
Emotions are as important as thoughts, not above nor below. Just two composite of consciousness. They both defines one's actual consciousness.
