And above all, what India has to give to the world is this.
In India the same competing gods had been struggling with each other for supremacy, but the great good fortune of this country and of the world was that there came out in the midst of the din and confusion a voice which declared एकं सद्विप्रा बहुधा वदन्ति — "That which exists is One; sages call It by various names." It is not that Shiva is superior to Vishnu, not that Vishnu is everything and Shiva is nothing, but it is the same one whom you call either Shiva, or Vishnu, or by a hundred other names. The names are different, but it is the same one. The whole history of India you may read in these few words. The whole history has been a repetition in massive language, with tremendous power, of that one central doctrine. It was repeated in the land till it had entered into the blood of the nation, till it began to tingle with every drop of blood that flowed in its veins, till it became one with the life, part and parcel of the material of which it was composed; and thus the land was transmuted into the most wonderful land of toleration, giving the right to welcome the various religions as well as all sects into the old mother-country.
