What do we really want out of life? That's what I would ask. Is acquiring these things a secret or understanding our drive, our desire to acquire these things?
A simplified example: Let's say Seth wants candy and I give it to him every time he wants it. He associates good behavior with candy. One day he is good, but he doesn't get candy. Is the ultimate secret envisioning the candy so he can get it, or does he try to see why he wants it so badly in the first place? Let's say I give him the candy, is anything solved? Next time I don't give him candy, will he be stuck in the same place again? My question to you, will you be stuck in the same place again? Doesn't need an answer, just look out for yourself and see if you do or not.
So, do you spend your understanding what it means to love or spend your energy looking for someone to love you? Do you spend your energy understanding and caring why you are afraid of being alone or spend your days filling that void with people? Do you spend your days envisioning how to have massive, unlimited wealth, or do you try to understand your own urge to acquire wealth so much, and why has money taken so much importance? Granted if there is no food on the table, if you are homeless, then these are different motivations. But the rich man using the secret to be richer, what is the true purpose of this?
I still think the greatest and only secret we can unravel is the secret to ourselves -- not what the universe wants to give us. Until we understand ourselves, we can never understand how much we impose our desires into everything externally and everyone else. When you unravel this in yourself, then you will be able to see a life uncomplicated and unmarred by what we want out from ourselves, others, and external things. Then it will stretch out to your perceptions, and you will see a very different world, a world untouched by society's desires - and perhaps you will perceive an interconnection with the world that is very difficult describe. You don't have to watch a movie, or go to a seminar or any of that. It's always been there inside of you, hidden cryptic by the thoughts, attitudes and perceptions you have about life.
