The way in which units of movements (karaṇas) are harmoniously brought together into a composition (vinyāsa); compositions into a sequence (krama); and  sequences into a series (sāraṇī) is called harmonious flow (samūdāya-vahanam). The art of creating the samūdāya-vahanam is accomplished by creating symmetrical divisions (vibhāga) and arrangements   (tanu – lit. frame) which maintain a natural and rhythmic flow by balancing the breaths between the units of movement (karaṇa) and the static postures (āsana), maintaining equal number of counts into every composition (vinyāsa), equal breaths between every parts of the sequence (krama) and finally blending sequences into series (sāraṇī).
