Man's moral obligation to God? There are two things I struggle with in your reply.
1. How is what you are describing not just having a better attitude? What has fundamentally changed? And is it really realistic to expect someone to always have a good attitude? If not, how is what you're describing any different than simply "try to be a more mature person and regulate your emotions better"?
2. If it were possible to detach yourself from your frustration, wouldn't you also detach yourself from your joy? If you do not listen to your thoughts and emotions, don't you become something inhuman and neutral? That's assuming it is even possible, and I have never seen anyone who could do that. Not even monks, who meditate for their entire lives.
It seems to me that you are overlooking the fact that our perspective is more than just our thoughts. It's also our biology. What you're describing is like a form of meditation, where you allow your thoughts simply to pass without judging them, and without judging your life's experience. But judgment is programmed into us as a living being because judgment is part of making good decisions. If there is no difference between tripping over a hose and not tripping over a hose, maybe there is no difference between walking into traffic and not walking into traffic. You say you can apply your intelligence from a place that does not need drama, but we don't react the way we do because we seek drama. Pain is a signal that something is wrong. If you trip over the hose your body is startled, and the neuro-chemical networks that evolved to teach you not to trip over things because you could get injured or be vulnerable to predators kicks in. The whole idea that you can ignore this seems foreign and unlikely to me. Can you ignore a dog barking in your ear? Can you have open surgery done without any medication for pain? Can you lose a loved one without crying, and if so, would you even want to? I feel like this idea of having selective control over our emotions and thoughts is unrealistic. If you can truly do that you are a miracle, but I am very skeptical, having tried these things myself.
