I once read a book on pornography additions by a fellow named Collins who as a recovery currently work as a therapist helping others dealing with this addiction. He related a story where one of his clients, after some success in controlling his urges for a little while, in a frenzy. The client told him that he's really distraught, because he is hit by such a strong urge right now. What had happened? As the client and been driving down the road, he noticed a pornographic magazine lying in the gutter or the side of the road, which had triggered a full attack. As Collins puts it, only an addict would notice a magazine thrown out stuffed in the street. Obviously if we spend the whole day repeating in our heads "I'm not thinking about it...I'm not thinking about it" we have reached a self defeating stage. I'm just pointing out that as an addict, I truly find that the strangest even remote things can be triggers. We have to be prepared. The gemara says a women should not put out her clothes to dry in public, because someone might see them and come to have promiscuous thoughts about her. I once heard someone make the following point: the chazal tell us that techeiles is blue because it is to remind us of the ocean, which in turn should remind us of the sky, which in turn should remind us of the kesei ha'kavod. People wonder, wow isn't that a little far fetched? All those steps? Kinda interesting that nobody ever questions the gemara about women's clothes. It all depends on where our brains are trained to connect dots to.
