Vedana is unfortunately usually translated as “feeling,” but I tend to think of it as reactivity - something happens, you react immediately and always, with “want it,” “don’t want it,” or with total ignorance, BUT you DO react each and every time (as right now!). Then you try it out with perception - “what do I know about this, how can I use it.”
Many have reacted with relief upon seeing and working with this chart by Andrew Olendzki:
