Advaita Vedanta is a type of Hindu philosophy. This philosophy teaches that we are all part of one big thing called Brahman. This means that everyone is part of the same "oneness". This means that your soul (atman) is part of the same thing as everyone else's soul. We are all connected and part of the same big thing. This means that we should treat each other with respect and love since we are all part of the same thing.
