The starting point of Buddhism and the Noble Eightfold path. Right view is seeing things without preconceived perceptions, or the filters we have all developed, to see beyond the initial view. It is seeing the causes behind the suffering, the reasons behind sickness and ageing. It is knowing that which we see regardless of appearance, length of existence is impermanent, just as everything else is. A basic understanding would include karma, it causes and effects. Also that everything that arises whether physical, vocal or thought is impermanent. That suffering will happen, whether it is sickness, ageing, death, unsatisfied craving or any of many other types, but these too are but temporary phenomena.
