So this post isn't about PTSD. Well it is, kind of.
Here is the yoga wisdom of the day
We do yoga poses that put us in strain or imbalance specifically to train the mind to be able to calm itself when we arrive at a real life situation that causes the same physical response.
i.e. next time you panic, remember how when you had your feet over your head and somehow your breathing and heartbeat came back down to normal.
