This is a bit complex issue.
The key is that each person will who is on the Path will start seeing the futility of certain activities and that really depends on the individual. One may not yet be an Anagami, but one may see the futility of reading fiction, for example, as I did long ago.
– Another person may still like to read fiction, but may lose the desire to watch TV, for example.
It is not that one loses all kama raga at the moment of attaining the Anagami stage. One will lose the last bits of leftovers at the at moment.
Eventually, one sees the unfruitfulness of doing any types of sankhara, when getting “sabba sankharesu anicca sanna” at the Arahant stage.
– That is what is meant by, “Sabbe sankhara anicca“.
– As I mentioned in a previous posting, An Arahant lives only for the benefit of others. He/she can only see the futility of any worldly action. Of course, most of us cannot even begin to comprehend that. And one should not try either.
It is a gradual process to get there, and each person will progress in one’s own way.
