Is there a Buddhist 'noninterference' concept?

My attempts:

First of all on interference which means action:

"'I am the owner of my actions (kamma), heir to my actions, born of my actions, related through my actions, and have my actions as my arbitrator. Whatever I do, for good or for evil, to that will I fall heir'...

"A disciple of the noble ones considers this: 'I am not the only one who is owner of my actions, …

Whatever they do, for good or for evil, to that will they fall heir.' When he/she often reflects on this, the [factors of the] path take birth. He/she sticks with that path, develops it, cultivates it. As he/she sticks with that path, develops it and cultivates it, the fetters are abandoned, the obsessions destroyed."

— AN 5.57

So non-interference arises through cultivating the path.

"And what is the cessation of kamma? From the cessation of contact is the cessation of kamma; and just this noble eightfold path — right view, right resolve, right speech, right action, right livelihood, right effort, right mindfulness, right concentration — is the path of practice leading to the cessation of kamma.

"Now when a disciple of the noble ones discerns kamma in this way, the cause by which kamma comes into play in this way, ...

.. The path of practice for the cessation of kamma should be known.' Thus it has been said, and in reference to this was it said."

— AN 6.63

Non-interference comes through desiring cessation of contact to cessation of kamma. The most noble of all (actions)kamma is ending of kamma.

When then can there be inteference? When one is fully enlightened i.e. when ones actions do not lead to any further kamma, and those actions are performed from metta, karuna, mudita.

To interfere means that one has a view on things and when one can be sure that the view created, is not from ignorance, then one can interfere.

Needless to say acting out of compassion is skilful etc. but not the path of the noble disciples but path of the bodhisattva.

Any why is non-interference desirable? From following it an arahant may arise that would benefit multitudes.

That’s my take on it.

I think you already answer your own question by mentioning impermanence. Why act upon something that will slip away between your fingers anyway, without anyone having the slightest control. Phenomena both mental and physical are uncontrollable and ungovernable. Interfering with them will not bring anything good out of it. Interfering with phenomena will bring suffering in the end. When i use the word interfere here i mean after the 7th link in Dependent Origination where craving, attachment and becomming happens. That will only lead to suffering.

Instead non-interference is what one should practice meaning observing phenomena arising and passing away. The practice of insight meditation is your answer. As you mention yourself one should work on oneself and develop oneself instead of trying to change the world. Interfering with e.g. politics, environmental protection etc. will only treat symptoms since the root cause are Greed. Only that can be reduced by working on ourselves trying to develop the mind.

Let me try to give another example. One is sitting in insight meditation and observing phenomena. One is not mindful for a moment and the mind gets sucked into the maelstroem of e.g. a mental formation. Then when mindfulness returns one will see that suffering is gained through interfering with phenomena. When seeing that over and over the mind naturally begins to let go and just observe phenomena without interfering, engaging them.

I dont know if this answers your question. I think the term non-interference might not directly be found in the texts under that name but its a derivative from the practice of insight meditation or a result of the impermanent nature of phenomena.

By the way i think its good that you mentioned the doctrine of Anatta. Everything just becomes problematic when an I, Me of Self is added to the equation. This have also been discussed recently. Take a look at this question here. You might be able to take the same perspective here that when adding an experiencing, permanent entity or Self to the equation then suddently you have "someone" that interferes.
