To pray is not to use special language; it is the sound of a cry or a laugh rising from ordinary days. Formal or official words can often be lifeless. To pray we need to return like children to an elemental language of soul, to something close to song, to chant, to playground singing.
The spiritual journey is one of continually falling on your face, getting up, brushing yourself off, looking sheepishly at God and taking another step.
