Unconditional love is known as affection without any limitations. It can be also love without conditions. This term is sometimes associated with other terms such as true altruism, complete love, or "mother's/father's love." Each area of expertise has a certain way of describing unconditional love, but most will agree that it is that type of love which has no bounds and is unchanging. It is a concept in ones mind comparable to true love, a term which is more frequently used to describe love between lovers. By contrast, unconditional love is frequently used to describe love between family members, comrades in arms and between others in highly committed relationships. An example of this is a parent's love for their child; no matter a test score, a life changing decision, an argument, or a strong belief, the amount of love that remains between this bond is seen as unchanging and unconditional.
In religion, unconditional love is thought to be part of the Four Loves; affection, friendship, romance, and unconditional.In ethology, or the study of animal behavior, unconditional love would refer to altruism which in turn refers to the behavior by individuals that increases the fitness of another while decreasing the fitness of the individual committing the act. In psychology, unconditional love refers to a state of mind in which one has the goal of increasing the welfare of another, despite any evidence of benefit for oneself. The term is also widely used in family and couples counseling manuals.
