Hi Chaim, welcome home!
The Gemoroh says in B"K מבעה זה האדם a person is ratzon. Hashem -who controls absolutely everything, gave us one thing: RATZON, that and nothing else. The more ratzon you have [for ex: to stay clean for 90 days] the more you are living. But if you think that YOU have the ability to control the y"h, then you're in trouble. Letting go doesn't mean c"v to cool off your ratzon. Rather it means to rely totaly on Hashem that
HE will give you hatzlochoh!
The result of that is -like the Chovos Halvovos says, מנוחת נפש הבוטח -total calmness. The y'h and especialy the addiction thrives on stress. But once you have bitachon he's a goner, because not only does the stress dissapear but you actually automaticly get the siyata dishmaya that you need. (How and why is a whole discussion in itself)
Being proactive about the lust addiction is a remedy for the utter helplessness of falling into that deep pit of weakness.
This is so true. In fact, this is our mission in life. We most definitely have to focus on it and always be proactive. {In fact the same people who say "Let go..." also say to be very very involved.}
"Wow! Isn't that so terrible the way that lady is dressed! I can't beliieve someone would dress like that in public. Maybe I didn't see correctly? So I'll look again just to make sure... nope I was right that is really not proper to be so bare...
That could lead latter to checking out a site which features that particle of clothing that "offended" my "righteous" indignation... and so on
The same for "checking" reading materials for "bad" parts and then getting caught up in reading them, when I knew that the author or publisher surely put things like that in
In my humble opinion this is a different issue. I personally have a lot of experience with this particular trick of the dirty despicable vicious menuval. First of all it needs to be exposed for what it is. Once you realize that it's the menuvals tactic, you can conciously avoid it.
It's also very important to recognize that you're an addict. Because the fact that you're an addict obviously gives you a blanket פטור from being mashgiach on everyone else problems. You just have to explain to the y"h that Hashem has other people to take care of these things; you have an official exemption.
But I don't think it has to do with letting go. Ad'raba part of taking action is avoiding triggers.
Hatzlochoh Raboh! and Chazak Ve'ematz!
