Truth exists outside also of the measurements of the mind. According to Krishnamurti meditation belongs to Truth. And meditation will not belong to reality. He says: 

Meditation is to find out if there is a field which is not already contaminated by the known.³³

          Krishnamurti thinks that mind will not cease to measure till it completes its measurements. Mind measures the world of encounter with its own frame and within the terms of the known. This measurement will be in the form of comparison and contrast. This known knowledge will belong to the past. Present’s measured with a reference to the past. A healthy mind tries to know only the knowable and will not try to know the unknown. When we encounter the unknown there will be a crisis.

          Krishnamurti expects an order in the world of reality. This only will achieve our progress further in the field of meditation. Generally, world of reality is world of thought. Unless there is an order in the world of reality we cannot achieve progress. And reality is the projection of our mind. If at all we wanted to explore the unknown our mind shall have in itself the ordered thought and reality as the project of mind. And thought is a response from memory. The process of thought is reactive in nature. It is the centre of memory. Every stimulus elicits challenges from our memory. The thought process in Krishnamurti’s philosophy is a challenge-response phenomenon. Thought requires a stimulus either from within or from without. Absence of stimulus cannot result in a thought process. Memory is one such source.
