The only way for a martial artist to succeed in breaking many bricks lies in their ability to “aim beyond the bricks”. If he focus his mind on the bricks he will not succeed. He will fail to succeed not because he lacks the technique or physical strength, it is his mind that fails to break the bricks.
In the same way we can “fail” to see the obvious because our attention is fixed.
Are you able to see where your attention is resting?
