Usually, and mainly in the West, it is interpreted as a feeling related to the affection and attachment, and resulting and producer of a range of emotions, experiences and attitudes.
In the philosophical context, love is a virtue which represents all the goodness, compassion and affection of the human being. You can also be described as actions directed toward other (or toward oneself) and based on the compassion, or as actions directed toward others and based on affection.
