The ego is a funny thing.
It just keeps on and on growing.
When we are babies, kids, there is hardly any ego.
But as we grow up and mature, and earn money, and attain fame and status, the ego swells bigger and bigger.
Oh a fat paycheck? Ego boost. A new car better than the neighbour’s? Ego boost. Double promotion at work? Double ego boost.
The more we apparently achieve, the more we think about ourselves, and greater the ego boost.
But funny it is then, that we achieve the foremost greatness, when we become One with all of Creation, when realization is attained i.e. the greatest of the greatest achievement, then the ego promptly falls to zero!
