Remembering past lives

How is it that I do not remember anything of my past life? This can easily be explained. I am now speaking in English. It is not my mother tongue, in fact no words of my mother tongue are now present in my consciousness; but let me try to bring them up, and they rush in. That shows the consciousness is only the surface of the mental ocean and within its depths are stored up all our experiences. Try and struggle, they would come up and you would be conscious even of your past life. - Swami Vivekananda ( Parliament on 19th Sep 1893 )
