Swami Vivekananda, the knower of the East and the West, in his first speech after his return from the West said,
If there is any land on this earth that can lay claim to be the blessed Punya Bhumi, to be the land to which all souls on this earth must come to account for Karma, the land to which every soul that is wending its way Godward must come to attain its last home, the land where humanity has attained its highest towards gentleness, towards generosity, towards purity, towards calmness, above all, the land of introspection and of spirituality —it is India.
Hence have started the founders of religions from the most ancient times, deluging the earth again and again with the pure and perennial waters of spiritual truth. Hence have proceeded the tidal waves of philosophy that have covered the earth, East or West, North or South, and hence again must start the wave which is going to spiritualise the material civilisation of the world. Here is the life-giving water with which must be quenched the burning fire of materialism which is burning the core of the hearts of millions in other lands. Believe me, my friends, this is going to be. (CWSV, vol.III, p. 105)
