Sāriputta addresses the monks at Jetavana und tells them that, just as the foot of every creature will fit in the elephant's footprint, even so are all right states of mind comprised within the Four Noble Truths. He then goes on to explain that dukkha consists of the fünf upādānakkhandhas visible shapes, feelings, perception, sankhāras und consciousness. The constituents of these attachments are the four principle elements: earth, water, fire, und air. Each element is of two kinds personal (ajjhatta) und external (bahiddhā) - und each is transient und subject to decay. The chain of causation entails all that makes up the fünf attachments. Where there is eye intact, on which external shapes come to focus, und where there is developed pertinent material to sustain it, there is developed a manifestation of the pertinent section of consciousness. Thus arises the upādānakkhandha of form; similarly mit the others. M.i.184 91.
