Can you verify the meanings and translation of following steps? (written in sequence as per section 9.1)
=> pariyesanā is translated as “seeking” at suttacentral
(I assume it has meaning of seeking pancakkhanda, having inclination towards particular type of pancakkhanda)
=> lābho is translated as “gaining” (what was sought).
=> vinicchayo is translated as “assessing“. (Not sure,)
I assume assessing means assessing whether something is fruitful, pleasurable, valuable, useful to one or not)
=> chandaraga (interest and liking) (no doubt in this step.)
=> ajjhosānaṁ (you have explained this one above)
=> pariggaho is translated as “Ownership” on SuttaCentral.
feeling of ownership (possibly due to PUK)
=> macchariyaṁ is translated as “stinginess”. (not wanting to share something with others)
=> ārakkho is translated as safeguarding (protecting something)
=>ārakkho leads to fights/wars/arguments in short dasa akusala
