 Feeling. The second collection includes the aggregates of  sensation or feeling (vedanā-skandha) and defines the  quality of the impressions that result from contact between the sense and its object. Sensations are generally divided into pleasant,  unpleasant and neutral and depend on the sensory modality in which  they originate. As internal mental states, sensations are both  conditioned by, and conditioning of, the habitual tendencies of past  karmic activity.
