Well, I did it...hid away all food drink and muktzeh and especially technology [except the stopwatch], cleaned the table and swept the floor, then sat down for six hours and a few extra minutes. (I figured if it's something to do specifically with having learned for exactly six hours, better to have a mini nevuah while I'm still learning).
It was interesting, the first four hours I was getting up and sitting down (book in hand), feeling sleepy feeling thirsty, even some intrusive lust. The last hour and a half was...calm, happy, almost had a neilah feel. Which is hilarious because it was only six hours.
I think the six hour mark was around Isaiah 40:17 (no, I didn't
just read Isaiah with the Artscroll/Stone Tanach translation for six hours. Though it was a good part of it.) Here is my mini prophecy, after finishing the chapter:
"Think nothing"
and the rest i'm not sure if counts:
two half-posuks:
"הנוטע אוזן הלא ישמע"
"המלמד אדם דעת"
and the posuk that follows:
"ד׳׳ יודע מחשבות אדם כי המה הבל"
I guess I'm supposed to not think about something. Or not worry about not hearing something, since my Teacher (best Teacher in every world) heard it. Or to pay zero attention to the nations of the world (look at 40:17) i.e. news/media/lust.
Or maybe it's a hint that I'm supposed to learn the mystical "think about nothing" meditation that Rabbi Aryeh Kaplan says is so dangerous.
