A single line from an artist can be the greatest revelation about his talent, intellect, knowledge and understanding.
I started many years ago developing this technique and i have since refined it steadily.
The amount of information which can be put into a single line is enormous and its even mind blowing to me at times what can be achieved by it.
This technique is one of my greatest pleasures, because it means to literally walk on a fine line. The longer you can hold this concentration the greater the reward. But beware, you will know yourself by doing this and some people might not feel as comfortable as i do after discovering themselves.
Failure is immediately visible and most people will be easily discouraged to continue.
One line is the absolute masterclass of any artform, because it means to simplify everything and bring it into one single point, which is constantly moving. Just like a human being living from beginning to end, being a single dot in history and carving his way into mankind.
The line you trace with your hand is the story that goes on in your head.
The clearer you see, know and feel, the greater the quality of the line will be, that flows out of your hand.
