Very briefly these are the five Aggregates. What we call a ‘being’, or an ‘individual’, or ‘I’, is only a convenient name or a label given to the combination of these five groups. They are all impermanent, all constantly changing. ‘Whatever is impermanent is dukkha’ (Yad aniccaṃ taṃ dukkhaṃ). This is the true meaning of the Buddha’s words: ‘In brief the five Aggregates of Attachment are dukkha.’ They are not the same for two consecutive moments. Here A is not equal to A. They are in a flux of momentary arising and disappearing.
