Ajahn Maha Boowa has "shed tears of joy" and declared his attainment of arahantship in front of a layperson (actually someone quite advanced in practice, it seems) as well as on camera a few years ago. This has caused a lot of controversy. See Ajahn Jayasaro talking about this here:http://www.youtube.com/watch?v=u76o7xZe ... L&index=39
I have recently been contemplating the similarity (in terms of being an "archetype" of a certain kind of monk) between Ajahn Maha Boowa and Maha Kassapa. There are a number of parallels between them. I may write some kind of essay about this later. But just a few points: both of them have followed the example of their teacher and attained high spiritual states; both have become charismatic leaders standing out of the normal Sangha community and sometimes taking initiative in "undemocratic" ways to achieve something; both have gone further than other monks in declaring their attainments openly and with force; both have voiced open criticism against other monks who were not part of their particular group. Often we can read: "Maha Kassapa. The monk that succeeded the Buddha as leader of the Sangha and convened the First Council." Well, he did not actually have the authority to do it, did he? And his authority was apparently not accepted by all. He also demonstrated his superiority over Ananda:"Beware, friend Ananda, or else the Sangha may further examine you. How is it, friend Ananda, was it you to whom the Exalted One referred in the presence of the Sangha when saying: 'I, O monks, can attain at will the four fine-material and immaterial meditative absorptions, the cessation of perception and feeling, the six supernormal knowledges; and Ananda, too, can so attain'?"
"Not so, venerable sir."
"Or was it that he said: 'Kassapa, too, can so attain'?"
"Yes, venerable sir."http://www.accesstoinsight.org/lib/auth ... 5.html#ch7
And referring to his own attainments, he stated quite frankly that it is not possible to hide them just like it is impossible to cover a mountain with a leaf. That is quite a statement, I think.
