The Shurangama Sutra
The Shurangama Sutra L53 The Mechanisms of Senses
In this session of the Shurangama Sutra, Khenpo Sodargye completes the detailed analysis of all six sense faculties by examining the nose, tongue, body, and cognitive faculties in terms of both their ultimate faculty and physical floating-dust faculty aspects. The nose-faculty, whose objects are openness and blockage, has an ultimate essence composed of the pure four elements and a physical form resembling a pair of talons. The tongue-faculty, whose objects are flavors, has a pure ultimate essence and a physical form described as a crescent moon, with different sensations at its tip and root. The body-faculty grasps at tactile objects and has a physical form shaped like a skin-covered drum; when there is contact it knows, when there is separation it ceases to function. The cognitive faculty, whose objects encompass all dharmas across past, present, and future, is given no physical analogy — because the mind defies material description. Khenpo then teaches that each faculty depends entirely on its objects: deprive a faculty of its objects and it becomes completely inoperative. This leads to a liberating insight: when one faculty achieves perfect penetration and all grasping ceases, the remaining faculties are liberated along with it — entering through one gateway liberates all six. The session closes with the example of Mahakasyapa, whose ordinary cognitive faculty and conceptual mind had long ceased, yet who perceived all phenomena perfectly through the pure ultimate faculty — a model of the realization that awaits practitioners who follow the path of the Shurangama.
