What is worth desiring from the world? What is worth desiring from the world when everything is impermanent ?

I can't even desire Nirvana , because I never get it. Here it states that I can not say Nibbana as mine or me  or myself( I can not say I am in state of Nibbana and I can not say Nibbana as mine):


  “He directly knows Nibbāna as Nibbāna. Having directly known Nibbāna
  as Nibbāna, he should not conceive himself as Nibbāna, he should not
  conceive himself in Nibbāna, he should not conceive himself apart from
  Nibbāna, he should not conceive Nibbāna to be ‘mine,’ he should not
  delight in Nibbāna. Why is that? Because he must fully understand it,
  I say.


( I am asking this question to understand the depths of knowledge... I am trying not to take delight in asking such questions.Buddha says one should not even take delight in Nibbana.)
Let's forget for a moment about "I", and "wanting". Here are some:


Negative things:


Minimise or eliminate "suffering"
Minimise attachment, and craving, associated with suffering
Minimise defilements
Minimise fetters

Positive things:


Maximize wisdom
Maximise perfections
Maximise factors of enlightenment



Learn to practice the noble eightfold path.

Practice good deeds (and speech), and generosity, which are for example "a support for the mind".

I think that, when a monk is dying, another monk may be advised to remind him of his "attainments" -- perhaps it's such "attainments", and "good deeds", that are not (or that are less) impermanent.



As for "I can't even desire Nirvana , because I never get it" -- that seems like a contradiction, you know.

Imagine "I" is like a drop of water, and "Nibbana" is like an ocean. Then "I desire Nibbana" or "I can't desire Nibbana" is like saying, "I wish this drop of water would be as big as the ocean, as permanent as the ocean, but still be the same individual drop of water."

Then people around you are like, "Dude! Let it go! Put the drop in the ocean, already!" (or, depending on the school of Buddhism, maybe, "That drop of water is already like the ocean").

I think a reason why Buddhism teaches anatta is because it's the characteristics of "I" that are associated with suffering -- craving to have things is associated with suffering; seeing and being attached to (and wanting to be attached to) an impermanent "self" that's going to die is associated with suffering; and so on.

One advice, which I remember from long ago, is to treat your sense of self (or your body) like a wound -- you take care of it, you try to treat it so as to minimize suffering, but you don't love it, you don't become attached to it.  And you don't say "I can't want to be healthy because then this wound (my sense of self) would disappear."

Also there's some middle way, for example this sutta or this sutta imply that some wanting is "right".
