In ordinary day to day life when we see something our instantaneous reaction is to respond with like, dislike or just a neutral feeling towards what we have seen. This will cause passion (craving) or dispassion (aversion) or neutral feelings towards the object or the person.
All of these events happen at a tremendous speed in ordinary life and we may only be aware of lingering likes and dislikes, when we see an object. However they are a series of events, dependently arisen that cannot be separately seen under ordinary circumstances to an untrained person. The main reason for this is our distorted perception of the reality. We see everything as permanent, satisfactory and self (Figure 1).
Now how do we see this process as separate events, step by step or with precise clarity? This is what we train during insight practice, the observation of these separate events with precise clarity.
In a another sutta Buddha shows us the way to contemplate on these, when we see these events as separate steps, dependently arisen. Although this is a very short sutta, this I think gives us the main clue of the method of getting rid of ignorance with insight meditation.
( The same applies to the other senses too)
The Figure 2 shows the possible points of action that can be applied to this model that help to get rid of ignorance. The Foundations of Mindfulness: (Satipatthana Sutta), the contemplation of the body (kayanupassana), feeling (vedananupassana), mind (cittanupassana), and mental objects (dhammanupassana) which is shown in yellow bubbles in the flow chart. The contemplation of impermanence of the six senses and their respective stimuli is one of the main sections of the forth part of The Four Foundations of Mindfulness (dhammanupassana) is the key to abandon ignorance as said in sutta above. With wise attention (Yoniso manasikara), we can now contemplate onThe Three Characteristics (ti-lakkha.na), Impermanence (Anicca),Suffering or Unsatisfactoriness (dukkha) and Not-self or Insubstantiality (anattaa) and this is the is final common pathway of contemplation of insight. The ignorance and craving is completely destroyed after cutting through all the ten Fetters and by after ending of the Fermentations or Taints.
