which Dhammatalks are you referring to, can you give a link?
there is an interesting talk from an Arahant about his enlightenment:http://www.luangta.com/English/site/tal ... 2-5-45.pdf
It is certainly a very touchy issue. If we look at attainments Jhana and sotapanna, sakadagami, anagami and arahant.
If I would claim any of this as a monk to laypeople, I would entail pacittiya. But if I tell the laypeople, the way how I got rid of avijja, then would I actually claim that I am an Arahant? I don't think so. People who know the texts and descriptions will know, others won't.
If my intention however is to claim something with telling the people how I got rid of avijja, then I have an offense.
If I tell another monk that I attained this or that, and this monk tells it to laypeople, is there an offense? No
If I tell monks that I attained this or that, and this is recorded and then I myself put the recordings or transcriptions in book form, then I would entail pacittiya.
The question is here if an indirect claim is a claim that falls under pacittia 8. I would say if the Intention of the indirect claim is to claim something, then it is a pacittiya, if it is there only for teaching purpose to show the people the way out of dukkha, then there is no offense.
When one is teaching as a monk to laypeople, one should be careful, as long as there are kilesas, they tend to boast about ones own attainment, if there are no more kilesas, one cannot boast. Mostly the way it is done in Thailand is done indirectly, and I personally feel that this is not an offense. But as a monk one should be careful with this as well, as I said, as long as one has kilesas this is a tricky and touchy subject.
This is only my personal opinion.
