In Fikr no effort must be made to change the rhythm of the breath; the breath must be left to its own usual rhythm. One need not try even to regulate the rhythm of the breath, for the whole mechanism of one's body is already working rhythmically. So the breath is rhythmical by nature and it is the very breath itself which causes man to distinguish rhythm. What is important in Fikr is not the rhythm but the concentration. Fikr is swinging the concentrated thought with the movement of breath, for breath is life and it gives life to the thought which is repeated with the breath.
