It is said that Bodhidharma came from India and bought what became Zen Buddhism to China. 
He supposedly impressed the emperor and other monks by staring at a wall in a cave while sitting still for 9 years. As a result he lost the use of his legs.
For the other monks who were engaging in his deep meditation techniques but growing physically weak, he invented the martial arts combat training of Kung Fu. This was to strengthen the body to endure the rigorous hours of endless meditation.
When he died it is said that years later his tomb was opened and all his followers found was one old sandal.
Q: So what's the Lesson of all this?
Observe: All those years of monks (including Bodhidharma) spent in hard physical training of Kung Fu so as to just sit for endless hours in wasteful meditation of twisting the mind like a pretzel----(Ever learning, and never able to come to the knowledge of the truth. 2 Timothy 3:7) followed by death (All go unto one place; all are of the dust, and all turn to dust again. Ecclesiastes 3:20).
Q: Was it worth it?....staring at a wall for 9 years.....and all that was left in his dust was a sandal.....
Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life.
Romans 5:18
No deep meditation techniques,
no wasted time staring at a wall,
no rigorous martial arts training required.
