All my life, pre Gupta, I would ruminate for ages over something which caused me to react as if threatened by danger. I would also overreact when I felt a danger threatened me…
I would relive it, turning it over and over in my mind, replaying it with differing reactions from myself as in “I wish I’d said……” or “ I wish I’d done…..” Sometimes this process was repeated for a period of weeks, even, and occasionally popping back up after months or maybe years. This was my way of getting it out of my mind and coming to terms with it. Or so I thought. 
Post Gupta’ing:
Nowadays, for a start it doesn’t require me to get things out of my mind when I’ve been in real danger or even when mildly threatened by someone’s behaviour.
Because it just goes, automatically disappears as soon as the threat has gone.
2 Recent Examples:
I was walking with JessC along a narrow country lane (no footpath) and a car came racing up towards us.
We both just stepped up onto the grassy bank and waited for it to pass. (We are always on a lead when anywhere near a road.) And another time we were walking in one of our favourite local woods when a big dog charged us, snarling and snapping. No one was on a lead this time and the big dog got a mouthful of JessC’s hair (luckily only hair, it’s long and curly. ) I snarled back at the dog and waved my stick in the air, which made him beat a hasty retreat, thank goodness,
The person with that dog said ‘No harm done’ so I replied ‘Only because JessC’s hair forms a protective layer, otherwise it would have been more serious.’We all walked on, his dog on a lead now. But both JessC and I were calm throughout what had been a real attack.
Pre Gupta it would have taken me ages to regain my calm. 
Another, Slightly Different Example:
Occasionally I do catch a virus. So I accept that I have a virus and I allow the symptoms to take their course and wait patiently for my immune system to fight the virus off. If the symptoms become difficult to bear I would then treat them with over the counter medications. So far, so good. I have recovered from the virus a lot quicker than my friends who had the same one. I think because my parts didn’t jump in and send out ‘fight’ messages causing stronger symptoms.
So calming my amygdala and keeping them calm by continuing with my meditations etc doesn’t stop me from dealing with real danger or threats.
It stops the danger from dealing with me.
