Breath is prana, which you will use to elevate your sense of awareness through focus.
Bring your breath into your feet and hands, linger it, watch it move through the neurons of your body.
This will teach you to split your focus between the single point that mind uses for focus and the multiplicity of points that prana is.
Breath will teach you the nature of all things eventually. It is said that Shiva was choked by poison and his breathing cessated, hence his blue skin.
