From my point of view, every one of us is capable of peace and happiness. If the mind is not cluttered with dark or negative thoughts, and if there are no blocks to your emotions, and if there is not something out of whack in your thought processes, you will revert back to your ‘default setting’…happiness or contentedness. The devil is in the details, however, as if it were that simple, everyone would be content/happy, and no-one would suffer emotional pain for any length of time. The reality is, however, that many of us go through much pain and suffering, and have no idea why. And, if you can’t understand why you feel the way you do, you have no hope of fixing it, unless by some random chance of fate it fixes itself.
Often, when someone reaches a point where their emotional pain is unbearable, it is due to a culmination of years of build-up to that point. And, whatever method they used in the past to relieve the pain no longer works, or only works at a terrible price. But, I am saying this not to cause despair, but to cause hope…of course achieving relief, at this point, is not going to be a snap of the fingers. But, relief is still possible, and peace and happiness are still attainable…it just takes a bit more self-understanding.
