The ordinary person, perceives Nibbana, he conceives it, he does not discern it/ fully understand it.
It’s like he has the right idea but then conceives his idea as THAT Nibbana.
He has a concept (ion) of it, HE is pregnant with the HIS idea of Nibbana…but that is not that Nibbana because it is in regards to HIM one way or another. Although he is close to it, so to speak.
It seems that back in the day, those higher mind concepts, those background general perceptions, were more widely known, and so people could in fact develop there minds in jhana, or brahmaviharas , or overcome sensuality etc without the Buddhas teaching, without right view.
For those who had developed minds as such, it was pretty easy for the Buddha to teach, because there was but little dust in their eyes.
For us,however, we have come across the idea of more general background phenomena/ appamanas, through the Buddha’s teaching, which is right view, and so I would say it’s pretty much unlikely that someone nowadays, who is trying to develop jhana , brahmaviharas etc would not have the ideas of right view in mind also, anicca dukkha anatta etc, and thus there would unlikely be someone who has developed jhana etc without being one with right view.
We have all the right information, but we misperceive it; our minds are way more proliferated into the senses. We are at this time closer, in general, to the animal realm, than the god realm.
Or the human situation now, in general ,is more directed/ pulled towards the senses,like animals; as opposed to the opposite direction of the god( brahmaviharas) abides.
Go with the senses and maybe one day, one can be as ‘free’ as a bird.
