by Jiddu Krishnamurti: The mind that has put its house in order, has understood the nature of knowledge. Such a mind is completely silent. And that silence has no cause. You see, “silence” can be illusory; it can be put together by a thought that is determined to be silent. You have the silence between the two whistles of a train, the silence between two notes, between two noises, between two sounds, between two thoughts – but that kind of silence is still within the realm of cognition. But when the mind is completely silent, it isn’t even aware that it is silent. If it were, it would merely be playing tricks. The mind that has put its house in order is silent. That silence has no cause and, therefore, has no end. Only that which has a cause can end. That silence – which has no ending – is absolutely necessary, because it is only in that silence that there is no movement of thought. It is only in that silence that that which is sacred, that which is nameless, and that which is not measurable by thought, is. And that which is, is the most sacred. That is meditation.
