In the blink of an eye
It all depends on your point of view.
In Feudal Japan a great General led his army in battle against a small village.
Knowing the General's reputation all of the citizens in the village fled, except for an old Monk, who refused to leave his beloved temple. Upon hearing this news, the General decided to go to the temple and see for himself just what kind of man the Monk was.
As he rode through the gate and onto the temple grounds he found the Monk standing there waiting to meet him. The Monk greeted him warmly, as he would any other guest, and he offered the General all of the hospitality his temple had to offer.
Realizing that the Monk did not fear him at all the General said, "Do you not realize that you are talking to a man who could kill you in the blink of an eye"?
To which the Monk replied, "Do you not realized that you are talking to a man who can be killed without blinking an eye"?
Remember: “In life everything depends on your point of view, and the view always depends on where you stand”.
