This "Publisher’s Note" introduces a revised edition of a book exploring Swami Vivekananda’s lesser-known contributions to the physical sciences. While celebrated as a spiritual leader, the text highlights his remarkable accuracy in scientific observation and his deep understanding of contemporary scientific thought.

The book specifically emphasizes Vivekananda’s "intuitive" genius, arguing that intuition is a vital, yet often overlooked, tool for scientific discovery. The author, himself a man of science, draws parallels between Swamiji’s philosophical insights and modern scientific works to demonstrate how training the mind can unlock unseen power.

Published by Sri Ramakrishna Math, Chennai, in May 2012, this volume commemorates Vivekananda’s 150th birth anniversary, aiming to inspire further study into his scientific legacy.
