Knowledge vs experience -from the Gita

I was watching random episodes from our very own Mahabharatha series...

In one scene (one of the last episodes), Krishna wants Bheeshma(lying on a bed of arrows) to instruct Yudhishtira about what makes a good king.
Bheeshma wants Krishna to do the task instead, as he is the all-knowing. Krishna says, "I have all the knowledge, but not the experience".

Think about Krishna's answer. The more you think about it, the more things hit your mind.. I find all answers to sins and adharma in that one line.

"Evil" in itself is static. Knowing the tricks of robbery, tantra, and so on is knowledge -which is something every one should possess. Ignorance is no longer a bliss -Ignorance is crime. Ignorance is denial of duty. A stable mind is one that knows all the evils, and that is the mind that also knows how to stay away from evil.
On the contrary, an ignorant mind is the one most susceptible to crime and scandals.

Experience is what a mind gains by training itself. An ignorant mind gains knowledge through (mostly) bitter experiences.

The discussion on this topic is endless. I can never express the abstractness of this topic in words! My ignorance fails me yet again!! And again... and again!!!
