Uppaluri Gopala (Yuji) Krishnamurti (1918–2007) is the most radical and shocking teacher who does not fit into any existing spiritual and secular frameworks and ideas. At the age of 49, he underwent a monumental mutation that spectacularly changed his perception, the functioning of all his senses and the physiology of his body down to the level of cells and chromosomes. All accumulated knowledge was completely swept away from him, including the idea of an independent self and the society opposing it. Unlike later conversations, in these early conversations Yuji describes in some detail the process of entering the natural state, a vision that revealed and the biological changes his body had undergone. These conversations also include in-depth explanations of the spiritual traditions of humanity. “I reveal all the secrets,” Yuuji says. He never spoke about it again. Among the participants in the conversations was the famous quantum physicist David Bohm.
