This is a special form of intensive retreat in Zen tradition --
In 7 days, the master and the students are living together, the master takes care of the students 24 hours a day.
We get up at about 4AM, then through out the day,
we continuously do walking meditation, then sitting meditation, then walking, then sitting, then lunch. after lunch, the same routing again, untill dinner. After diner, again. Sleep at about 11pm.
The master lectures all the time, and do sitting meditaion and walking meditation with students together.
The master lectures difference ways and words to each individual student.
Talking is forbidden. But sometimes master do force students to speak up when the master sees fit.
You might not be totally enlightened after 7 days, but you will be a different person for sure! [There is the possibility that you get Enlightened within 7 days - given that you have been practice buddhism for a ling time, but feel frastrated with no progress. All it needs, is just a word from the master, which inspires you - because Enlightenment comes within you, not from outside, even not from the meditation!]
Please open your mind, don't try to judge without trying to understand it.
I personally gurantee it. All it takes, is completely immerge yourself into the Dharma, your body, your mind, in every second, 24 hours a day. This is not a retreat where you take it easy and enjoy life. Here you actively attack your evil deeds and completely devote yourself to the goal of Deliverance.
