Changing from inside
Regular practice of deep diaphragmatic breathing changes its practitioner from inside by changing what the practitioner knows and undrstands on one side and feels on the other. The mechanism through which transformation happens is one track mindedness of the practice. When a person is engaged in deep breathing, she/he is conscious of breathing and breathing alone. All he thinks is exhalation and inhalation. Everything else must be excluded from the conscious mind. Such a practice develops the penetrative capacity of the human mind freeing it from the day to day problems of everyday existence for the duration of the practice. This freedom alongside enhanced penetrative power combine to put day to day issues of human existence in perspective.
