Questioner: Why is memory an impediment?
Krishnamurti: Memory, as the identifying process, gives continuity to the self. Memory then is an enclosing, hindering activity. On it the whole structure of the ego, the I, is built. We are considering psychological memory - not the memory for speech, facts, for the development of technique and so on. Any activity of the self is an impediment to truth; any activity or education that conditions the mind through nationalism, through identification with a group, an ideology, a dogma, is an impediment to Truth.
Conditioned knowledge is a hindrance to Reality. Understanding comes with the cessation of all activity of the mind - when the mind is utterly free, silent, tranquil. Craving is ever accumulative and time-binding; desire for a goal, knowledge, experience, growth, fulfillment and even the desire for God or Truth is an impediment. The mind must purge itself of all its self-created impediments for supreme wisdom to be.
