People today have a fragmented view of the world, seeing its diversity but not the unity that underlies it. This fragmentation, writes Shiv D Talwar, is at the root of ethnic conflict, environmental degradation and other problems. To address it, he proposes a radical new form of education, directed towards unity in diversity. To get there, he draws both on ancient spiritual wisdom - including the Vedas and Upanishads from India, the creation story in the biblical book of Genesis, the ninety-nine names of God in Islam, Jewish mysticism and the writings of Lao Tzu - and modern physical and biological science. Religions are many but their wisdom is one, and that wisdom converges with the findings of science as well. Beyond natural science and social science, there is also a spiritual science, which Dr. Talwar outlines in this book. Through spiritual science, humanity can develop its consciousness of infinite and infinitesimal ultimate reality. A second volume will address spiritual technology: the application of spiritual science to individual health and harmony.
