Here is the meaning -- the real meaning -- of XP :
Juzan, the zen disciple, was in the habit of taking on students. When travelling through the land, he would stop in some particular location, and lecture about the meaning of zen, or how it may be found throughout nature. As he concluded these lectures, he would raise up his pointer finger, and thrust it upwards.
After a while, he noticed that one student began punctuating his speech with this same motion, and cautioned him against the practice. The student nodded vigorously and promised to stop. Juzan noticed that the student's promise was short lived as he resumed the mimcry of his teacher.
Annoyed, Juzan took the student aside and asked him to give his opinion on an issue of the day. As the student spoke, he began to raise his pointer finger, and in one swift motion, Juzan lopped it off.
After the wound healed, Juzan again took the student aside and asked him to speak. The student spoke, and began the familiar motion once again. When he realized he could not extend his finger, he was enlightened.
