Master Engo (Yuanwu Keqin) , answering the question "What is Zen?" Expressed himself as follows: “It's is directly in front of you at this moment, I convey it to you in its entirety. For an intelligent person, one word is enough to guide him towards the truth, but even then, a mistake can creep in. When truth is expressed by means of pen and paper, or clothed in the form of sophism; in these cases it eludes us even further. The great truth of Zen lives in everyone. Look inside and search for it there without any help.”
