The Five Aggregates: Sensations

The second [of the Five Aggregates] is the Aggregate of Sensations (Vedanākkhandha). In this group are included all our sensations, pleasant or unpleasant or neutral, experienced through the contact of physical and mental organs with the external world. They are of six kinds: the sensations experienced through the contact of the eye with visible forms, ear with sounds, nose with odor, tongue with taste, body with tangible objects, and mind (which is the sixth faculty in Buddhist Philosophy) with mind-objects or thoughts or ideas. All our physical and mental sensations are included in this group.
