That is indeed a good sutta that explains the way to Nibbana. I just read it. Thanks for that reference.

It is essential that one must learn about the Tilakkhana from an Ariya to get to the Sotapanna stage.
– However, “learning about the true explanation of Tilakkhana” is not enough, as Tien pointed out with the example of Ven. Potila that I discussed in a past post.
However, if one truly believes that one has an understanding of the “unfruitful nature” or the “anicca nature” one could be a Sotapanna or a Sotapanna Anugami. One could probably confirm for oneself by comparing whether one’s behavior has changed.
The best example I can give is about one trying to quit smoking. So, he learns about the bad consequences of smoking.
– If he really gets the idea that it is dangerous to keep smoking, he would at least cut down on smoking.
– But it may take some time to totally quit, by really getting the “sanna” that it is indeed dangerous to smoke.
– However, if the message DID really register in his mind, sooner or later, he would totally quit. Then there is no doubt.
