Everything is relative

[Plenum]

It comes back to seeking love in every moment. I wonder if buddhist "detachement" is the same as Ra "acceptance".

That sounds reasonable.  With full 'acceptance', the amount of emotional charge associated with an event or situation becomes non-measurable.  One can then take the most loving action possible, with a clear mind, and not seeing any possible separation.

That kind of 'relationship' could be classified as 'detachment' or 'true objectivity'.

It may have a more specific reference in Buddhist terms, which I'm sure you'll expand upon, if I've missed the mark.

The thing is, 'acceptance' or 'detachment' is not something you can 'do'.  It's the end result or final state of the processing of the emotional charge associated with personally impinging events - "someone taking something personally'.

So trying to force acceptance without doing the actual inner work is kinda pointless and non-productive.  It's like trying to love something without understanding why you, deep inside, truly loathe it.  The issue is not the lack of love, the issue is the rejection of the thing as it currently is represented to you, via the inner relationships you have to that thing/concept.  Love/acceptance happens automatically once you balance the reasons for the rejection.
