Uppaluri Gopala Krishnamurti (9 July 1918 – 22 March 2007), better known as U.G., was an Indian speaker who questioned the state of enlightenment. Although many considered him an "enlightened" person, U.G. often referred to his state of being as the "natural state". He claimed that the return to the natural state is a rare, acausal, biological occurrence, which he referred to in his own life as “the calamity”. Because of this, he forbade people from pursuing it as a spiritual goal and urged them to just learn to live under the stranglehold of thought and self-consciousness.[1]
He rejected the very basis of thought and in doing so negated all systems of thought and knowledge. Hence he explained his assertions were experiential and not speculative – "Tell them that there is nothing to understand."
