YaMa list 5 behaviours that explain how one should relate to the external world:
1. AHIMSA – non violence, in your thoughts, words, actions. It’s important to control your behaviour to avoid falling into actions that are not Ahimsa. Being Vegetarian or Vegan is very much Ahimsa too. If
you eat animals your belly becomes a graveyard, and certainly you do not want that.
practising the higher limbs of ashtanga yoga – dharana, dhyana, samadhi – requires a tremendous amount of energy or prana.
the good balance between the two.
Awareness without guiltiness is very important.
