Swami Vivekananda: The genuine orator exercises a sort of hypnotism over his audience. I have listened to many orators, Indian, English and American; but Keshub Chunder Sen is easily the greatest of all.
Quoted by Charu Chandra Banerjee in a speech at Dhaka Purva Bangla Brahmo Samaj; "Brahmananda Keshub Chunder Sen: Testimonies in Memoriam" compiled by G.C.Banerji, Allahabad, 1934.
