Sri Jibankrishna Or Diamond said this quote

Two thousand and five hundred years ago Lord Buddha announced, ‘By self- exertion we will achieve ‘Nirvana’, and then Hinduism announced, ‘By self-mortification and self-exertion we shall achieve the supreme knowledge. But this supreme knowledge means knowledge of oneness. No, not the knowledge of oneness, it is rather oneness only and that is achieved spontaneously.
