Well Mr. @Johnny5 Not sure if this is a compliment or criticism. lol
But just because YOU think you can't accomplish this feat, doesn't mean it's impossible for others. I also find it odd you think I can't handle a week in isolation for the purposes of meditation. You don't know me nor the work I've been doing these past several months to better myself(Do nothing meditation, strong determination sitting, vegan diet). If an ordinary (but talented) individual like Leo can spend 10 days and 90 hours meditating in complete isolation, I'm pretty sure I can go a week.
And why do you think what I am proposing is ridiculous? Is it ridiculous for Leo to do his yearly 30 day solo retreats? Is it ridiculous for the Marathon Monks of Mt. Hiei to do the incredible things they do to strive for enlightenment? If those guys can do the things they do why is it so hard to imagine an ordinary individual to do a 300 day solo retreat? I'm pretty sure in 20-30 years I'd be more the mentally and emotionally capable to handle such a feat. Some people might need only 5 months to prepare, others may need even less.
Besides, my one year solo retreat is nothing compared to what the Monks of Mt. Hiei endure. I don't think I'll ever be able to hang with those guys. What they do is out of this world amazing. But I'm pretty confident, if I prepare properly, I(and many others) can easily do a 300 day solo retreat and come out on the other end a better person than they were before.
