By learning to observe without becoming involved, the pattern of stimulus-response which underlies most human behaviour can be broken. Little by little the realisation dawns that one is free to choose how to react in all situations … The grip of long-standing habits is weakened and replaced with a new sense of freedom.

~ Damien Keown

This … perception of impermanence … gives rise to the knowledge that even those things which seem most intimate to us – such as our emotions – are transient states which come and go. … From … detached observation it … becomes clear that even one's conscious mind is but a process like everything else. Most people regard their mental life as their true inner essence ( … ), but insight meditation discloses that the stream of consciousness is just one more facet of the complex interaction of the five factors of individuality, and not what one 'really is'.

all living creatures are entitled to respect in their own right, not simply because of the utility they may possess for other humans.

~ Damien Keown

Zen has a pronounced iconoclastic tendency, and regards the study of texts, doctrines, and dogmas as a potential hindrance to spiritual awakening, relying instead on humour, spontaneity, unconventionality, poetry, and other forms of artistic expression to communicate the idea of enlightenment
