Astanga Yoga in a beautiful diagram. Yama (abstinences- nonviolence, truth, nonstealing, restraint, non possessiveness), niyama (observances-cleanliness, contentment, self discipline, study, true self ), asana (postures), pranayama (breathing), pratyahara (withdrawal), dharana (concentration), dhyana (meditation) and samadhi (absorption).

Veganism fits in first yama-ahimsa or nonviolence.
