After the first edition was published in 1969, I visited U.S.A., Europe, Japan, etc., in October 1970 with Mrs. Rajeswari Raman, alone in April 1971, and in October 1972 and with Mrs. Raman in May 1981 delivering lectures, addressing group-meetings and holding discussions with scientists and leading astrological savants. In fact the highlights of these visits were the opportunity given to me to deliver a lecture at the United Nations, New York; and successful demonstration.
