The 3 most powerful words that can help in any situation of life are:
It doesn't matter...
Variations of this would be:
Leave it be...
Let it go...
Such things happen...
Never mind then...
anything that instantly takes your mind away from whatever is creating the feeling of unquiet, or is disturbing you, or making you feel crucified, or ruffling your feathers. Nothing that causes any kind of change in the otherwise serene and tranquil landscape of mind is worth it. In speaking these 3 words, you may not get instant peace, but it does put you onto the path, and slowly but surely you find the wrinkles smoothing out, the cloudiness easing off, and the clearness coming back.
