The foolish one is always under attack in his own perception.
The wise one is fully secure, he is not being attacked.
The wise man, therefore, has not really cut at the root of this world.
He has, firstly, cut at his own insecurity.
When you have cut down your insecurity, then you are no more a slave of the world.
You are no more standing in front of the world with the hope of fulfillment.
