Thanks for the sutta references, santa100.
On jhana, as David said, obviously some kind of indication is necessary to get the practice around and motivate people to meditate. And I sincerely wish from the bottom of my heart that more and more people can experience the blissful serenity of jhana which in my opinion is an extremely important step on the path. And if you have experienced jhana, fantastic, more power to you!
But the Internet is the wrong place for jhana claims. And the main reason is there are already more than enough self-proclaimed http jhana attainers, http stream winners, and http arahants, the vast majority of which we cannot verify due to the anonymity provided by the internet. A claim that cannot be verified adds little to the discussion.
By the way, I can enter the fourth jhana at will and I am also a millionaire.
Attainments are best divulged to a trustworthy monastic or lay teacher who is in a suitable position to assess your claims.
