People use emotion and feeling, interchangeably without understanding the real meaning .Actually both are different. I will explain how.
When a thought comes to the mind it creates an emotion in the body (Here the body means both the energy and physical body). There are only two kinds of emotion, one is love and other is fear. When the thought is about a person the emotion created is either love for the person or fear for the person. The situation is similar if the thought pertains to a situation or an object
The emotion created then produces a feeling in our heart. Joy, ecstasy, anger, envy, greed are different types of feelings created. Broadly all the feelings created can be clubbed under two categories, happiness and sadness. In short an emotion of Love produces a feeling of happiness and an emotion of fear creates a feeling of sadness.
