The mind has to be with the breath. That is the bottom-line. If the mind is not with the breath, the mind does not become empty.
Meditation is the main tool of the Spirituo-Scientific Temper. Unless one makes one's own mind empty, the ABSOLUTE TRUTH cannot be seen. The mind is the coloring agent of human being.
Meditation is a universal science: Science of making the mind empty & energizing the soul. More you do meditation, more stable your life will be (physically, mentally, emotionally & spiritually).
