Why are you confusing yourself with Advaita with Ahimsa?
In Sanskrit Dwi means two. Accordingly, as per one school of thought i.e. Dwaita, God and Man are different; they are not one! They are Two i.e Dwaita.
When Shankaracharya came on the scene, he proclaimed that there is no Two personas; God is not different from Man. God is embedded in every man. There is no Dwi. There is only one i.e. Man himself! And within every man there is God! And it is everyones duty to search for God not outside but within himself or herself.
There are no Suddha Advaita or simple Advaita! There are only Dwaita, Advaita, and VisishtaAdvaita! I will tell you at some other time what VisishtaAdvaita means! Ramanajujacharya is the proponent of VishithaAdvaita.
Dont Mix Gandhis, Aurobindos and JKs with these.
Now Ahimsa is totally different and has no connection with Dwaita, Advaita, or VishitaAdvaita!
