The Kabbalists reveal the very reason for our unhappiness in life. This reason is found in an age-old formula that was known to the Kabbalists and it concerns the dynamic of human desire and the influence of ego.
It works like this:
When the ego covets 100, it will work day and night to achieve 100. Once that 100 is achieved, the ego then doubles in size. Now it craves 200. It will now impel you to work and sweat around the clock, 24/7, until you attain 200. When the 200 is achieved, the ego automatically doubles in size and now that emptiness inside of you craves 400.
This cruel formula keeps chugging away so that a man will die at the end of his life miserable and sad at having only fulfilled half of his desires.
The more you seek, the more you sink.
The only way to achieve unending happiness (including biological immortal existence, which is our destiny) is by starving the ego. When you starve the ego, the emptiness inside of you shrinks. Now the desire of your soul, your true desire is free to blossom. You begin to seek out and acquire true assets, true gifts, true blessings, the kind that never wear out and never leave you.
This is how you climb the ladder of true success.
In other words, the ego makes you chase after everything that money can buy with the promise that you will be full of pleasure and happiness. The reason the thrill of a new car or a new house or new clothes eventually wears off, is because the ego has doubled in size. Now you are half fulfilled.
The conquering of the ego is how we acquire everything that is priceless and everything in life that money cannot buy.
