Whenever there is a conflict, the tension arises and the ego exists;' when there is no conflict the tension disappears and the ego disappears. Ego is not a thing -- it is just a tension.
The ego needs some problems. If you understand this, in the very understanding the mountains become molehills again, and then the molehills also disappear. Suddenly there is emptiness, pure emptiness all around. This is what enlightenment is all about -- a deep understanding that there is no problem.
Start living this moment and you will see that the more you live, the less problems there are. Because now that your emptiness is flowering and living there is no need. When you don't live, the same energy goes sour. The same energy which would have become a flower, is stuck; not being allowed to bloom it becomes a thorn in the heart. It is the same energy.
If you live, ego disappears. Life knows no ego, it knows only living and living and living. Life knows no self, no center; life knows no separation.
