This idea is not clearly found in any other religious system. They are all parts equally struggling to attain to the whole. The existence of the part is only for this. So, from the very first, Advaita had no antagonism with the various sects existing in India. There are dualists existing today, and their number is by far the largest in India, because dualism naturally appeals to less educated minds. It is a very convenient, natural, common-sense explanation of the universe. But with these dualists, Advaita has no quarrel. The one thinks that God is outside the universe, somewhere in heaven, and the other, that He is his own Soul, and that it will be a blasphemy to call Him anything more distant. Any idea of separation would be terrible. He is the nearest of the near. There is no word in any language to express this nearness except the word Oneness. With any other idea the Advaitist is not satisfied just as the dualist is shocked with the concept of the Advaita, and thinks it blasphemous. At the same time the Advaitist knows that these other ideas must be, and so has no quarrel with the dualist who is on the right road. From his standpoint, the dualist will have to see many. It is a constitutional necessity of his standpoint. Let him have it. The Advaitist knows that whatever may be his theories, he is going to the same goal as he himself.
