Are God and his personality mere imagination of the human mind? Or does He really exist with divine attributes? If He exists and has personality, what kind of person He is? Is He like us with physical bodies shaped by genome and acting in space-time? Or is He a transcendental personality beyond the comprehension of our tiny brains? This volume is an excellent presentation of two classic dialogues T. D. Singh had with two prominent Nobel Laureates in physics-Charles Townes and William Phillips. Charles Townes received the Nobel Prize in physics in 1964 for his discovery of laser and maser. He also won the Templeton Prize in 2005. His work on the laser opened the way to today's vast technological revolution and new frontiers of research in science. William Phillips received the 1997 Nobel Prize in Physics for using lasers to cool and trap neutral atoms which paved the way for scientists to design more precise atomic clocks and also to create the highly astonishing Bose-Einstein condensation T. D. Singh, who himself is a scientist with a Ph.D. from the University of California, Irvine, USA as well as a spiritualist in the in the Bhaktivedanta tradition of India, met both of them personally and had a significant exchange of ideas. He has been a pioneer in advancing science and religion dialogue from over three decades. The fine reflections of these remarkable thinkers of our times presented in this volume will help readers further shape their perceptions about the nature of the Ultimate Reality or God.
