Estimation of Plans

This is an untold story' from Mahabharat, published in a Sanskrit Magazine, many years ago. It goes like this:
Duryodhan is lying in the battle field, awaiting death, badly bruised by the wounds inflicted by Bhima. He kept his three fingers in a raised position and is unable to speak. All the efforts made by his men to understand the meaning proved to be futile.
Seeing his plight Krishna approached him and said
"I know what issues occupied your mind. I will address them".
He clarified that the issues are
a) not building a fort around his capital city,
b) not persuading Vidur to participate in the battle
c) not making Aswathama as commander-in-chief after the death of Dronacharya.
Krishna explained further that (a) Assuming that you built a fort, I would have asked Nakul to mount the horse and destroy the fort,
(b) If you succeeded in persuading Vidur to participate in the battle, I
would have taken the Sudarshan Chakra myself to
defeat him, and
(c) If Aswathama is made the
commander-in-chief, I would have made Yudhistir
angry.
On hearing this Duryodhan closed all the fingers
and within seconds he left his body.
Let me explain a little further. Many of us do not know that Nakul can drive his horse even in heavy rain without getting wet. He travels with such a speed between a drop and another drop, without
getting wet. Only Nakul can do this among Kaurav
and Pandav warriors.
It also seems that if Yudhistir
gets angry, everything that falls within the range of
his eye sight will be burnt.
Management Lesson: Properly estimate the plans
of the enemy and prepare for a counter attack well
in advance like Krishna
