To practice Zen means to observe the fact and process of knowing. Consciousness is the most visible face of our mutualized knowing, a knowing through others and within the proximal spectrum of phenomenality. To closely and dispassionately observe the activity and functioning of consciousness, it is necessary, additionally, to actualize a transformational ‘awareness-observing-consciousness.’ This is a shift in kind: a shift from a self- referencing, comparative consciousness to a non-self- referencing, non-comparative awareness. This ‘non-self-referencing, non-comparative awareness,’ allows us to attentionally notice and study, to deconstruct and reconstruct, the perceptual and organizational processes of consciousness. This process of deconstructing and reconstructing consciousness is called the Teaching of the Five Skandhas. The five attentional categories for the analysis of consciousness are: ‘Form,’ ‘Non-Graspable-Feelings,’ ‘Perception,’ ‘Associative Consciousness,’ and ‘Consciousness.’
