Emotions are not logical, rational or conscious, but they are a natural and useful form of subconscious communication. They tell us how we feel about something even when we are consciously unaware of how we feel.
The subconscious is the feeling mind, and emotional reactions are not necessarily rational when they are from the subconscious reactive level. The feeling is always the essential thing; not knowing that you have the feeling or whether It is the “right feeling.”
