AN 7.64 kodhana (anger), case 3 of 7 unclear what is meant by "profit" or "loss", and how exactly that sabotages what angry person wants (pali + english, derived from b. Sujato trans.)

The passage in question:


  “And further, an enemy wishes of an enemy, ‘O, may this person not
  profit!’ Why is that? An enemy is not pleased with an enemy’s profits.
  Now, when a person is angry—overcome with anger, oppressed with
  anger—then even when he suffers a loss, he thinks, ‘I’ve gained a
  profit’; and even when he gains a profit, he thinks, ‘I’ve suffered a
  loss.’ When he has grabbed hold of these ideas that work in mutual
  opposition (to the truth), they lead to his long-term suffering &amp;
  loss, all because he is overcome with anger. This is the third thing
  pleasing to an enemy, bringing about an enemy’s aim, that comes to a
  man or woman who is angry.


b.bodhi has:


  (3) “Again, an enemy wishes for an enemy: ‘May he not succeed!’ For
  what reason? An enemy does not delight in the success of an enemy.
  [95] When an angry person is overcome and oppressed by anger, if he
  gets what is harmful, he thinks: ‘I have gotten what is beneficial,’
  and if he gets what is beneficial, he thinks: ‘I have gotten what is
  harmful.’ When, overcome by anger, he gets these things that are
  diametrically opposed, they lead to his harm and suffering for a long
  time. This is the third thing gratifying and advantageous to an enemy
  that comes upon an angry man or woman.


In the other 7 cases in the sutta, specifics are given so it's clear what the person who wants the enemy to suffer, how their anger sabotages their desire and tends to get the opposite result. In the case # 3 above however, it's not clear what the Buddha had in mind for specific examples. I can think of some hypothetical situations that would meet that criteria, but they would just be guesses. 

Anyone think they know exactly what is meant here?
In AN 4.55 for example there is:


  When both are faithful and kind,
  Ubho saddhā vadaññū ca,
  
  disciplined, living properly,
  saññatā dhammajīvino;
  
  then wife and husband
  Te honti jānipatayo,
  
  say nice things to each other.
  aññamaññaṃ piyaṃvadā.
  
  They get all the things they need,
  Atthāsaṃ pacurā honti,
  
  so they live at ease.
  phāsukaṃ upajāyati;
  
  Their enemies are downhearted,
  Amittā dummanā honti,
  
  when both are equal in ethics.
  ubhinnaṃ samasīlinaṃ.
  
  Having practiced the teaching here,
  Idha dhammaṃ caritvāna,
  
  both equal in precepts and observances,
  samasīlabbatā ubho;
  
  they delight in the heavenly realm,
  Nandino devalokasmiṃ,
  
  enjoying all the pleasures they desire.”
  modanti kāmakāmino”ti.


The word in AN 7.64 is pacurattho which suttacentral's dictionary says is a compound:


  pacura (abundant; various; many) + attha (aim, purpose, goal; advantage, profit, benefit)


The translation as "profit" appears to have come from picking one of the meanings of the latter word.

I too can only guess at specific examples. From AN 4.55 I'd guess it includes all the requisites at least, and what they have to live at ease (phāsuka -- pleasant, convenient.), maybe heavenly pleasures too.



Reading the rest of AN 7.64, I think the whole sutta is a polemic against anger -- not a detailed explanation of how specific types of wealth are gained or lost. Looking through the verse at the end, anger seems to cause the loss of everything -- sleep, wealth, friends, reputation, conscience, life, etc.

So becoming angry may cause a person to lose anything and everything.
And perhaps it's easy to see why such a loss might please an angry person's enemy.

But I'm not sure why it points out that it would please an enemy ("what would please an enemy" doesn't seem to me a usual or recommended view-point of the suttas) -- maybe it's just meant as a synonym of "misfortune".
