That is correct. But one needs to realize the following.
– One gets “full control” only at the Arahant stage.
– A moral person (without miccha ditthi) has some control.
– That “limited control” become PERMANENT when one starts comprehending the anicca nature (that there is NOTHING in this world worth craving for). So, at the Sotapanna Anugami stage, one would NOT do “apayagami actions” even under strong temptations. A normal “moral person” is CAPABLE of doing “apayagami actions” under strong temptations. That is the key point.
– Then as that Sotapanna Anugami makes more progress, he/she will get to higher stages via deeper comprehension of Tilakkhana. Then rebirths in the kama loka, rupa loka, and arupa loka will be stopped in that order. Rebirth process (and ANY suffering) will be over at the Arahant stage.
