why one cause for five grasping groups

when we think the four noble truths and the first noble truth of suffering or in other words five grasping groups.

so there are five groups and one cause. desire.

and the cause of desire is feeling as given in dependent origination.

so five groups arising from one cause desire. desire arises from feeling. feeling arises from contact. contact arising from sense bases. sense bases arising from name and form. name and form arising from consciousness. consciousness arising from intentions. intentions arising from ignorance.

why five groups and one cause? is a difficult question to answer. but we know that there are ten causes defilements  for existence in sansara or continuation.

it should be noted that if we do not have desire then all the actions that we do whether good or bad will cease.
