Slowly, gradually you decrease your mind, by and by. If one percent is decreased, then you have ninety-nine percent mind and one percent no-mind within you. It is as if you have removed some furniture from your room - then some space is created there. Then you remove more furniture, and more space is created there. When you have removed all the furniture, the whole room becomes space.
Really, space is not created by removing the furniture, the space was already there. It is only that the space was occupied by the furniture. When you remove the furniture, no space comes in from outside; the space was there, occupied by furniture. You have removed the furniture, and the space is recovered, reclaimed. Deep down mind is space occupied, filled by thoughts. If you remove some thoughts, space is created - or discovered, or reclaimed. If you go on removing your thoughts, by and by you go on regaining your space. This space is meditation.
