If you follow the technique of vipassana as it is, properly; words aren't enough to explain how wonderful it is and I sincerely hope with every decent fiber of my being that everyone manages to do at least one 10-day course in their lives. I got back yesterday. Was intense. Glad I did it again, this was my 3rd course attended. I'll go back at the end of next year.
I'm still not enlightened. I really struggled with the seeds of doubt/bullshit of "Maybe this isn't the perfect time for me to do it. Maybe I'm not even worthy of this." and "I'm an old(returning) student, I'm the man, I know what I'm doing." and another slippery slope which derailed my progress/advancement with the practice entirely; not simply following the instructions and observing natural sensations as you're supposed to but instead searching for something 'special' something miraculous and amazing to save and inspire me. Which guarantees that won't happen. So, I've been humbled again and relearned what I learned the second time. But, overall I was vindicated in the sense that compared to how I was I'm definitely a changed man and have much more patience and equanimity and I'm far less negative.
I thought of many of you particularly @soon @Dazey @SoulMonster since you guys have expressed some level of intrigue in vipassana before. I hope you do it.
