Mindfulness-based cognitive therapy offers a similar level of protection against relapses of depression to antidepressants, according to the results of a new trial published in The Lancet.

I am not answering for Camellia, just giving my interpretation. Like buttercrabs above says, its not about stopping your thoughts, You basically want to dream in a save space. You let your thoughts happen, no matter what it is, if it is good or bad, the fact that you are doing this in a position of control on a neutral state allows your brain to let these thoughts happen without your emotions taking over and so you can let go of negative thoughts. In a dream you would wake up from a nightmare and during your regular day you would push these thoughts deep down again since you dont want to deal with these negative feelings at the moment. In a state of mindfulness meditation you can you can have negative thoughts without getting hurt.

The best example in imy opinion is to think of an browser. Your brain opens a tab for every memory you have. And attaches an emotion. The stronger the memory the bigger the tab, and the bad memories will be like a huge video playing. And sometimes they just start playing music and you desperately try to find the tab and close it. But the moment you close it it opens 4 new pop up tabs. Depression is kind of like your brain freezing like the browser, it is not enough to close a tab, but you kind of have to restart the whole thing. And now you can close the bad tab that is to much for you.

So mindful meditation allows you to have those bad thoughts of failure if they actually happened or even if they were just imagined go away by experiencing them again in a save mode where you are able to look at them, realize they are not important and not save them.

The one important rule is that bad memories dont just have one tab but you basically create a lot of tabs and ever time you feel bad about an experience again you create a new one. So a person who had a lot of shit to deal with wont be ok after one session. You have will have to think some thoughts seemingly over and over again since your brain made so many tabs for them and close all of them one after the other.

For most humans our dreams have the function of reliving our day and dealing with those things. But medical conditions or just overfilling our day with tv and things like that make it hard for our brain to process everything at night and the result is it builds up. YOu usually have the weekend or vacation to reset. But if you spend your friday night drinking and your vacation drinking on spring break your dreams are not able to handle all your thoughts. So mindful meditation gives you half an hour a day where you can work off a lot of the thoughts that have build up over time.

Hope this helps a bit. If you cant understand my explanation because of bad expression feel free to ask.
