it is said: “One sees, hears, smells, tastes, makes body contacts, or a “dhamma” comes to one’s mind. These do not “just happen”; they happen due to reasons (causes). They come about due to kamma vipāka”.
Hi Siebe,
Kamma vipaka is the resultant citta of the 15 out 18 ahetuka citta (7 akusala vipaka (unwholesome resultant), 8 kusala vipaka (wholesome resultant), and 3 kiriya (functional)). Thus there are 7 vipaka citta which is due to akusala ahetuka citta and 8 vipaka citta which is due to kusala ahetuka citta from our five senses (see, hear, smell, taste and body contact). For example if you see someone which is a close friend which you like, you will extend good will and friendly smile (kusala vipaka citta) towards that friend. But if that person is not a close friend and is one which you do not like then your action may be hostile towards that person (akusala vipaka citta). As you can see, the friendly or hostile action towards the person depends on conditions which are past experiences that provides a result (vipaka).
As all ahetuka (without root) citta are kammically indeterminate (abyakata), they do not consitute a good or bad kamma.
Fundamental knowledge of Abhidhamma on citta, cetasika, rupa and piticca sumuppada would be helpful in understanding dhamma.
Hope this helps
