Until the end of his life at the age of ninety, Krishnamurti-the world teacher-traveled the world speaking as a private person. The rejection of all spiritual and psychological authority- including his own- is a fundamental theme. A major concern is the social structure and how it conditions the individual. The emphasis in his talks and writings is on the psychological barriers that prevent clarity of perception. Because his subject is all-embracing, the Collected Works which are in 18 Volumes- are of compelling interest. Within his talks in any one year. Krishnamurti was not able to cover the whole range of his vision, but broad amplifications of particular themes are found throughout these volumes. In them he lays the foundations of many of the concepts he used in later years. The Collected Works contain Krishnamurti`s previously published talks, discussions- answers to specific questions- and writings for the years 1933 through 1967.
