As per of the phenomenology of the mind there are two hard processors “Head & Heart” and two soft processors “Stomach and Sex” that build; readjust; update and grow new regularities in your emotions.
When we say head it is both about matter “The Mind” and the metaphysics “The Conscious”; the process of senses judgments; calculations and illusions as well; which further move to heart (interests; choices; fear; phobias; guilt and feeling of sinfulness) which finalizes the shape of feeling and mood and then the emotions are portrayed.
The Soft processors do have the additional role of the physiology as per of eatables and sexual needs of a person which reshape and process “Emotions”.
