Why do we suffer in this world? What is pain? Why do bad things always happen to good people?
Actually, it happens to everyone; it's all relative to their situation and personal condition.
Are earthquakes good or bad? An earthquake hits a town and kills thousands of people leaving a heap of chaos and destruction. It's also a part in the cycle of the eco-system, a function of plate tectonics that creates mountains, oceans, volcanoes and etc.
Are volcanoes good or bad? You can't really say because from one aspect, they tend to destroy anything within a 50 km radius with rivers of lava and plumes of ash that cover the sun's rays, destroy vegetation and leave a trail of destruction behind. But this process is also a function of the eco-system which creates new islands, mountains, and the ashes of which help nourish the soil which is better for new vegetation and reforestation.
Rat poison is deadly when eaten, but arsenic used in rat poison is used in some medicines like Arsphenamine to treat syphilis.
So good and evil is all relative to your perspective.
But let's dive deeper into this idea. Let's talk about human suffering: disease, famine, loss of a loved one, war, divorce, disputes, conflicts, depression, anxiety, failure, fear, etc. What mechanism is there that determines who gets what, who gets a bigger share of the wealth pie, who will become the next president, who will live on the street, who will die in a car accident in his twenties and the race car driver who will live to be a hundred and twenty?
One thing that is definitely obvious is that we can't predict the future, but we can alter it. By changing the way we look at things. Instead of thinking on terms of loss and failure, we can change our perspective to even see death as a celebration. Another thing that is certain is that none of this was an accident and we're right on track, like it or not.
The universe is run by an Intelligent Consciousness that determines who gets what, based on each person's personally installed and configured software. It's like climbing a mountain versus a walk in the park. The more determined you are to reach the top, the more obstacles you will face than the person who prefers to bask on the beach.
But the weird part is, pain and suffering happens to everyone, young or old, rich or poor. Who says rich people don't have problems? Who says people living in one part of the world are better off than those who live in other parts? First of all, it must be said that wealth distribution is fluid and it moves throughout societies and goes hand in hand; one day you're picking your dinner out of a trash can and the other day you're getting a thousand dollar manicure for the evening's cocktail party, and vise versa (these extremes are especially true for the ambitious mountain climbers). Secondly, who says that being filthy rich relieves you of all the problems in the world? We all face the same amount of trouble, regardless of race, gender, class or age. The rich always has to worry about keeping his money, where to invest it, how to protect it, or perhaps he has a deadly form of cancer, or he's the depressed kind, or his kid is a socially dysfunctional lunatic or etc (lifestyles of the rich and the famous?!). While the poor guy has to worry about tomorrow's grub, or the future of his children, or the delayed rent, or fixing the hole in the roof, or etc. It doesn't matter who you are or where you live, it all depends on how you look at things. A hole in the roof can be a problem, or it can be the key which helps you develop your talent in "roof-hole-fixing" and making a small business out of it.
EVERYONE has to face some kind of suffering and if they tell you they don't, they're either lying or they've got an extremely rich insight. Either way, this is the foundational idea. The truth is put very well by this famous phrase: "life is a mountain, not a beach!"
We're not here on a vacation; we're on a journey on the way to the top. Like it or not, it's a road we all go down, and it's a peak we will all eventually reach, sooner or later. Life is an experience we all have to discover, and even the slowest of us must go through enough suffering to eventually reach this summit. Pain and suffering is part of the experience. It's a wake up call to those who are asleep and just another hurdle for those training for the race.
"No guts, no glory" or "no pain, no gain"... and as the story of life moves on, we will all live to discover the beauty behind the gore.
You must study hard to gain a degree from the top university, which is simple enough for us all to understand; but this riddle takes on another painful dimension when we are diagnosed with a deadly disease.
"Why me?" "what did I do wrong?" we always tend to ask when we are hit with such terrifying news. And thus brings us to the next most powerful lesson to be learned: bodily malfunctions are wake up calls, it's a tool used by the living organism to knock sense into its unwary owner. It's the manifestation of an awakening consciousness of the body protesting against the foul foundations of human lifestyle and even perceptions. This is another discussion which is deeply connected to the topic: Cell Consciousness and its connection to the way we see the world.
