The Master said, ‘Leaning without thought is labor lost; thought without learning is perilous’ ~The Chinese Classics (chpt. 15)
What possible good can come from knowing how to do a thing if we do not understand when it is appropriate to act. Knowing your front door has a lock will not keep your loved ones safe from those wishing to do them harm. To know the how of a thing is not enough, we need to examine the why of it if we are to truly understand.
