This style of yoga is often quite dynamic, which requires the mind to stay focused in the present to be able to keep up. Focusing keeps you from drifting off and helps you to be present in your body rather than stuck in your head.
The term vinyasa refers to a specific series of movements that are frequently done between each asana in a series. These days – the vinyasa is up to the yoga teacher.
The length of one inhale or one exhale dictates the length of time spent transitioning between asanas. Attention is placed on the breath and the journey between the asanas rather than solely on achieving perfect body alignment in a pose, as in Hatha Yoga. The breathing style used is a relaxed diaphragmatic style of breathing, like an ocean sound which resonates in the throat (ujjayi).
