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.
2. SATYA – truthfulness, as also non illusion. Show and act as respectful toward yourself as much as the others.
3. ASTEYA – do not steal, do not desire what is not yours, what you cannot afford and what is a representation of futile happiness. Even towards those things you own do not have attachments and desire. In yoga we are taught that when we no longer desire something it will come to us by itself. This is also the case for Asteya. Since the root cause of taking what doesn’t belong to you is desire, when you give up desire for things, all sorts of wealth will come to you by itself.
