Daily Quote September 22nd 2007, Krishnamurti Foundations
You can see that those who pursue a system, who drive the mind into certain practices, obviously condition the mind according to that formula; therefore, the mind is not free. It is only the free mind that can discover, not a mind conditioned according to any system, whether Oriental or Occidental. Conditioning is the same, by whatever name you may call it. To see the truth, there must be freedom, and a mind that is conditioned according to a system can never see the truth.
A mind conditioned by a system can never see the truth—Collected Works, Vol. VI (211)
