Stillness is really another word for space. Becoming conscious of stillness whenever we encounter it in our lives will connect us with the formless and timeless dimension within ourselves, that which is beyond thought, beyond ego. It may be the stillness that pervades the world of nature, or the stillness in your room in the early hours of the morning, or the silent gaps in between sounds. Stillness has no form—that is why through thinking we cannot become aware of it. Thought is form. Being aware of stillness means to be still. To be still is to be conscious without thought. You are never more essentially, more deeply, yourself than when you are still. When you are still, you are who you were before you temporarily assumed this physical and mental form called a person. You are also who you will be when the form dissolves. When you are still, you are who you are beyond your temporal existence: consciousness—unconditioned, formless, eternal.
— Eckhart Tolle
