Question: Is the process of cleansing the mind a process of thought?

KRISHNAMURTI: Can thought ever be clean? Is not all thought unclean? Because thought is born of memory, it is already contaminated. However logical, however rational it may be, it is contaminated, it is mechanical. Therefore there is no such thing as pure thought, or “free” thought. Now to see the truth of that demands going into the whole process of memory, which is to see that memory is mechanical, based on the many yesterdays. Thought can never make the mind pure, and seeing that fact is the purification of the mind. Please do not agree or disagree. Go into it, go after it as you go after money, position, authority, and power. Put your teeth into it, and out of that comes a marvelous mind, a mind that is purged, innocent, fresh, a thing that is new, and so in a state of creation and therefore in revolution.
