Suddenly, in the bright moonlit night, a perimeter guard, a warrior protecting his Emperor shouts from across the barren piece of land, : "Stop, or I will kill you". To this, Bodhidharma replies: "I am here to speak Buddha's Words of Wisdom. I come in peace. I can feel no pain if you kill me. Please kill me if you wish at this spot where I had to stop and could not proceed."
Feeling challenged, the angry warrior proceeds to cross the barren land. His brisk walking is slowed down quickly by his feet sinking in the ground. Every step he took made him sink under the ground by a few centimeters. As he began to sink, he screamed for help. Bodhidharma held out his hands and pulled him out of quicksand. It is said that the warrior was enlightened.
The philosophy behind this is for one to think things through before committing to do something that one wishes to achieve. One must have an extraordinary sense of awareness to perceive our environment.
