Upādāna is normally translated as “clinging”. As far as I understand clinging means mostly for things one likes. Does upādāna also apply to things one dislikes? For example in my pancakandha, (i.e. things that happened in my present life) I have dislike to some things that had happened. Does it mean I have upādāna (i.e dislike in this case) for the things that happened in my present life?
Yes. Both tanha and upadana can happen with like or dislike.
– Tanha is the initial “attachment”.
– Then one may keep thinking about it and “keep it close” (in the mind). That second step is upadana.
For example, if you see someone you really dislike on the street, anger may arise in you. That is due to tanha.
– If you keep thinking about how bad he is, and his past actions against you, then you are “pulling it close” and making it worse. That is upadana.
