Avihimsa means non- harm and Akrodaya means non-illwill. This means the setting aside of certain unwholesome qualities such as enmity, anger, illwill, jealousy, envy, hatred, fear and resentment. It means the development of certain wholesome qualities (the four divine abidings) namely kindness, compassion, joy at others well being, equanimity and non-harm. One has to be kind and compassionate towards other beings. One has to be happy at the well being of others, as opposed to being jealous, and has to be equanimous, when the occasion requires it.
