Yoga has poses. And moving into a pose. And moving out of a pose. And moving from pose to pose. All yoga has flow, some smooth, and some with longer pauses.
Nothing I can write and no set of illustrations can substitute for instruction. You learn yoga from a person.
When you have developed a good understanding and feel for yourself doing yoga, then you refine poses and your practice by study.
Writing about a pose takes time, restudying the anatomy, and thinking about and practising how I teach to align and engage the pose. I will write about poses slowly.
Yoga is not only poses.
