The day and date of the visit of Sri Ramakrishna and the exact words exchanged between the two Supermen are recorded in the Gospel of SDri Ramakrishna graphically. Of course Sri Ramakrishna had the final words , since Vidyasagar said "Today I have learnt a very new thing" and conceded to the gratness of the virtually uneducated Sri Ramakrishna who remartked "Every other thing has become second-hand, only Brahman has remained ever unfathomable"!
