How to identify Pada Parama Persons?

As preached by Buddha there are four types of people in the world, they are ugghaṭitaññū, vipañcitaññū, neyya and padaparama. The last person is definition is here . Can anyone please guide me how how to identified the pada-parama type people. **Update** Based on the comments, I was looking for the definitions of above four types of people and finally found that in Sutta Pitaka -> Kuddaka Nikaya -> Nettiprakaranaya -> Desanāhāravibhaṅga. And the english translation is not yet done, but you can find the pali here . I've highlighted the important words in below quoted section from above sutta. > Tattha bhagavā ugghaṭitaññussa puggalassa nissaraṇaṃ desayati, > vipañcitaññussa puggalassa ādīnavañca nissaraṇañca desayati, > neyyassa puggalassa assādañca ādīnavañca nissaraṇañca > desayati. - nissaraṇaṃ = deliverance - ādīnavañca = danger - assādañca = attractiveness - puggalassa = person - desayati = lecturing / teaching So here are three main things in Buddhism which are assādañca, ādīnavañca and nissaraṇañca. And the details of how it relates to the path can be found in <a href="/redirect?url=https%3A%2F%2Fwww.accesstoinsight.org%2Ftipitaka%2Fsn%2Fsn22%2Fsn22.109.wlsh.html" class="external-link" target="_blank" rel="nofollow noopener">Sotapanna Sutta <i class="fas fa-external-link-alt fa-xs"></i></a> as below. > And when, monks, the Ariyan disciple understands as they really are > the arising and the passing away, the attractiveness and the danger, > and the deliverance from the five groups of clinging, he is called an > Ariyan disciple who is a Stream-winner, not liable to states of > woe,[1] assured of final enlightenment. So in summary, out of the the four persons three has defined the based on what to be taught. 1. ugghaṭitaññussa -> Teaching deliverance is sufficient. 2. vipañcitaññussa -> Teaching danger and deliverance is sufficient. 3. neyyassa -> Has to teach all three which are attractiveness danger and deliverance. 4. Pada parama -> Can not attain Nivana as he is the one for whom the words are the utmost attainment'.;Whoever, though having learned much, speaking much, knowing many things by heart, and discoursing much, has not penetrated the truth.
