SPIRITUAL GIANTS :

Naren Datta a 19th century Indian was one such ,who in 1893 came to the World Congress of Religion ,held in Chicago, U.S.A, and shook the world by his spiritual force , Ocean-vast knowledge and earned the name Tornado-swami.
More things to know and tell about is his GURU, Sri Ramakrishna who ,better be introduced ,here , by his disciple , swami Vivekananda himself;
`I had the rare fortune of sitting at the feet of one such Guru who could not write his own name without making more than one mistake , -yet I was not worthy of tying the lace of his shoes`.
He was not only spiritual and realised Saint . He was spirituality personified. By his mere touch 0r body-vibration ,Ramakrishna could transfer spirituality into another worthy disciple. Hard to believe ! Read Roma Rolland`s book on him to revise your opinions one divine man who told about multiple living worlds in 1883,three years before the invention of Radio-Telescope and declaring the certainty of other planets out-side our Solar-sphere.
