Hi Johnny,
No. There is no need to “maintain” an Ariya jhana; once attained, it is never lost.
The reason is that, for example, in the first Ariya jhana kama raga anusaya is removed. So, there is no way for kama raga to EVER come back to that mind. Therefore, it is a PERMANENT change.
On the other hand, kama raga is only SUPPRESSED when one attains anariya jhana (anusaya is still there). Even during that lifetime itself kama raga can come back, and one could lose the anariya jhana.
However, if one dies with the first anariya jhana intact, then one will be born in the corresponding brahma realm. Again, he/she will come back to human realm and can go to apayas too.
