Lin-chi's third stage is to "take away both the man and his objective situation. In other words, it is liberation from . . . the attachments of both subjectivity and objectivity. Lin-chi's famous 'Ho!' . . . often served this purpose."28 In a blow of a master's staff or a shout there is nothing one can grasp, either objectively or subjectively. This is the next-to-last stage in the progression toward liberation from the mind's tyranny. In the fourth stage we find the final condition, in which objectivity and subjectivity cease to be distinguishable. What this means is that there is no intellectuation at all, that the world simply is. As Dumoulin declares, "reality is comprehended in its final oneness."29 Or as the story says: Before enlightenment, mountains are mountains and rivers are rivers; during the study of Zen, mountains are not mountains and rivers are not rivers; but when there finally is enlightenment, mountains are again mountains and rivers are rivers. In this final state the distinction and confrontation of subject and object dissolve, as we are finally at one with the nameless world. Another of Lin-chi's famous dialectical categories is his "Fourfold Relationship possible Between Questioner and Answerer or Between Guest and Host." The point of the structure he sets up is to elucidate the interaction of master and novice, but he does so using metaphor of host and guest--where the host represents the universal Self and the guest the ego-form self.30 Lin-chi's sermon on the subject went as follows: _A true student gives a shout, and to start with holds out a sticky lacquer tray. The teacher, not discerning that this is an objective circumstance, goes after it and performs a lot of antics with it. The student again shouts but still the teacher is unwilling to let go. This is . . . called "the guest examines the host." Sometimes a teacher will proffer nothing, but the instant a student asks a question, robs him of it. The student, having been robbed, resists to the death and will not let go; this is called "the host examines the guest." Sometimes a student comes forth before a teacher in conformity with a state of purity. The teacher, discerning that this is an objective circumstance, seizes it and flings it into a pit. "What an excellent teacher!" exclaims the student, and the teacher replies, "Bah! You can't tell good from bad!" Thereupon the student makes a deep bow; this is called "the host examines the host." Or again, a student will appear before a teacher wearing a cangue and bound with chains. The teacher fastens on still more chains and cangues for him. The student is so delighted that he can't tell what is what: this is called "the guest examines the guest._"31_
