indeed it is required to show an underlined watchtower and bookstudy book. It does not mean you have to study though. It is neither going to make you a better person. Regular meeting attendance is also required. But that is really it. In my case (my disfellowshipment lasted less then one year) I definitely was worse on the day that I was reinstated than the day that I was DFed. When I was DFed, I wanted the elders' help, and I got a kick in the butt. The appeal comittee gave one kick in the butt more, just to make sure... Funny thing as well, you go to the elders to get help, and their idea of 'helping' is... organizing a trial by the judicial comittee where you 1st have to prove you deserve that help. As my 'proves' were not strong enough: Ciao. Thank you for asking our help, but we are not going to help you out of your darkest depressive days, oh and, by the way, as you have followed our recommandations about friends in the world very well, nobody out there is going to help you either. It is a cold dark world I was kicked in to. So I had lots of time (I was a quite active JW before) to examine the doubts that came up. I also had lots of time to get over my cold feet to visit the websites about the witnesses, and lots of time to order Ray's books and to read them.
When they called me for the meeting for reinstatement, they were only interested in that particular thing for which I was DFed. No interrogation about my lifestyle the last few months, nothing. That meeting did not even last 10 minutes. I could have done anything I wanted, I was accountable to no one! And nobody has ever asked how I survived these months, if I gave in to alcohol, drugs, immoral conduct, not even my parents. (I did not, but I could have). Needless to say that this proved to me there was no Holy Spirit involved in all of this. If I was not disfellowshipped, I might never have woken up.
Dear elders, thank you for help. Please help kick more of my bros and sisters in the butt the same way as you helped me.
