It was found to be in conformity with the principles which are at the core of Buddhist vipassana practice. Two characteristics of Sunlun are its employment of sensation as the object of meditation and the intensity of practice. The adoption of sensation was never the result of a deliberate intellectual choice. It arose naturally as an organic part of the actual practice. But now it is possible to understand why sensation contributes towards the efficiency of the method.
Sensation lies at the interaction of mind and matter.
As such it is the best object of meditation to help the yogi establish mindfulness of the body, of sensation and of consciousness, namely kayanupassana, vedananupassana, and cittanupassana. It does so because it is at the root of all these stations. It is the non-mnemic element in perception and does not depend upon habit, memory and past experience. Therefore it is closet to the requirement of vipassana which avoids the concepts which are the basis of habit, memory and mnemic perception. A poem written after one month of intensive Sunlun meditation.
