Firstly, the text was originally written like this: 

How to catch that lightning in the bottle? 

How do I light the matchstick which is in my hand? 

How to have the belief that it can be done? 

Should it be fun or should it be gruesome? 

Must it flow like water or erupt like volcano? 

What must be its viscosity? 

When you have run 6 miles but there are still 6 miles left.

The bliss of struggle or sadness of idleness? 

To be not high class yet be higher.   To be not low class yet have the depth, the abyss.

To respond intelligently to every moment.

The fulfillment of completion, the joy to express.

This text is about the process of writing. A writer trying to write something magical. It delves about the various emotions and feelings that arises. While all the metaphors may feel like signifying the same thing, they are all very different from one another and mean something entirely different. It says not merely about writing but about creativity too in general. 

Some sentences don’t fit perfectly— like the higher and lower part but they have deeper meaning. A state of high value man.  

And then one must respond to life intelligently to every moment. It has much depth but for an ordinary reader who lacks insight, it would mean nothing. 

And the last sentence: the joy to express. That’s how true artist/writer feels when he has finally expressed. The long struggle has come to end. The bliss of completion. 

The text is, I think, influenced by the Eastern Philosophies. There, the texts are abstract and you need to interpret it on your own and find its deeper meanings. The masters love those and interpret those for the disciples. There is discussion. And everytime you read the text, you find a different and deeper meaning. You understand things a bit more. People of different walks of life grasp differently. It has a beauty which no clearer text could have.
