What's fascinating about this to me is that this teapot can teach us a lesson or two about how pressure/frustration/stress builds and accumulates in our own lives.
So, let's examine this a bit more.
First, there are often disturbing things that we deal with that instead of letting go, we dump into our teapot (the back-parts of our minds/heart). For example: working with someone who goes out of their way to either get you in trouble or sabotage you efforts.
All day long, things that affect us negatively usually gets dumped into our sub-conscious teapot instead of being dealt with consciously and released.
Lastly, when we've had all we can take and the pressure inside the teapot grows so much that it seeks an outlet, we blow. All the pent-up frustrations and emotions just push their way past our often rational mindset and find the release they craved. Unfortunately, if there is anyone caught in the way of this eruption, they will get burned.
Teapot Training 101
Health Hazard - One of the most deadly things about stress is the damage it can have on your health. Just as the lime build-up accumulated from water sitting in the teapot begins to eat away at it from the inside, unreleased stress does the same to you.
Use Communication - Most of the times, we begin accumulating stress by not being upfront and clear with people we're dealing with, so we end up stuck with this negative energy. Whether with spouse, children, friends, co-workers etc, learn to be clear on your position concerning what you want done, or what can be expected of you. Let them know "this works for me" or "This can be done
in this particular timeframe but without this" etc.
