What is knowledge, I wonder.

Formless, odorless, weightless and colorless, I guess.

Eyes and ears gather this stuff, essence of daily observations we do.

Gather, sift and sort items well to store in that knowledge well.

 

 

Knowledge is like the diamond in the mine

No one knows even if is not there.

Having knowledge is a great preparation to life

Putting it to work is what makes a change to the world.
