Removal of kama raga is a REQUIREMENT for the Anagami stage.
– But the removal of kama raga is NOT SUFFICIENT to attain Ariya jhana or even anariya jhana. There could be Anagamis without the ability to get into any jhana.
Getting to jhana is something that requires a focused effort.
– Of course, some people who had cultivated jhana in the recent past lives can get into jhana without much effort. But those would be anariya jhana.
The easiest way to verify whether one has even the first Ariya jhana is to watch an adult movie and see whether one does not get any sexual thoughts (an X-rated movie would be a better confirmation).
