Yeos asked: “When one attains an anariya jhana AND does not lose it ” how to behave for not losing it – Panca Sila and not acting with dasa akusala it’s enough?”
To attain jhana one must abstain from both dasa akusala and at least suppress kama raga. Jhanas correspond to mental states of brahma realms, and thus one must have the mindset of a brahma, who do not engage in sex (they are unisex, i.e., no male/female brahmas).
– Also see the response to upekkha100 below.
Ascendance to Nibbāna via Jhāna (Dhyāna)
Rest of your question: I just answered in the other post that you asked essentially the same question.
Upekkha100: I have revised #8 of the following post to provide a better explanation of what happens to one who has attained anariya jhana:
Ascendance to Nibbāna via Jhāna (Dhyāna)
From there:
- One who abstains from akusala kamma and kāmaccanda, can cultivate rūpavacara or arūpavacara jhāna. With those mahaggata kusala kamma (mahaggata means higher), one WILL be reborn in rūpa or arūpa lōka at the next cuti-patisandhi transition., not at the death of the current physical body.
- However, one must not lose that jhāna until that moment, which means through possibly more births as a human within the current human bhava.
- This also explains why some people can easily get to jhāna. Those had cultivated jhāna in recent human births within this human bhava.
- However, if it is an anāriya jhāna, one has not been released from the apāyas, since one has not removed avijjā by comprehending Tilakkhana.
P.S. I have not yet found a Tipitaka reference for the effects of mahaggata kusala kamma. Here is a short desana by Waharaka Thero for those who understand Sinhala:
