Moving to the ‘purana kamma‘ stage happens depending on the number of samyojana that remain intact. In the following, we will consider a human in kama loka.
- A puthujjana enters the ‘purana kamma‘ stage with all ten samyojana intact. Thus, the likelihood of getting to the ‘nava kamma‘ stage is high.
- A Sotapanna enters the ‘purana kamma‘ stage with seven samyojana intact. Thus, a Sotapanna’s mind will still move in the “Aniccaṁ vipariṇāmi aññathābhāvi” direction. However, the likelihood of reaching the ‘nava kamma‘ stage is lower, since he has three fewer samyojana intact. A Sotapanna’s mind does not attach with the three ditthi samyojana (i.e., with ‘wrong views’). That is why a Sotapanna is incapable of doing ‘apayagami kamma.’
- An Anagami will not enter the ‘purana kamma‘ stage even though he has five samyojana intact. An Anagami has eliminated the five samyojana that bind one to the kama loka; therefore, he will not generate ‘kama sankkappa‘ to attach to the ‘kama sanna‘ in the ‘kama dhatu‘ stage. Thus, an Anagami‘s mind will stay in the ‘kama dhatu‘ stage. See, for example, “Upaya and Upādāna – Two Stages of Attachment.”
- The above statements (for an Anagami) also hold for an Arahant, of course. In addition, an Arahant‘s mind will not enter rupa loka or arupa loka either, since it has eliminated all ten samyojana. See “Loka and Nibbāna (Aloka) – Complete Overview.”
I recommend reading those posts carefully. Feel free to ask questions. This is what is needed to become a Sotapanna.
