Everyone has heard about the soul. But most people don't really have a good understanding of the soul. That is a cause of all kinds of problems, because the soul, or conscious living force, is who we really are. This series of essays covers the most important aspects of the science of the soul: who and what the soul is, where he comes from, where his real home is, and his eternal relationship with God. In August and September 2006, I wrote a series of 32 essays on Bhagavadgītā 2.13. This is such an important śloka that my spiritual Master Teacher Śrīla Prabhupāda spoke on it more than any other verse of the Vedas. Therefore I selected it as the theme for my podcast for almost two months. The complete series is presented in this book. To attain happiness, spiritual advancement or anything worthwhile in life, we have to understand our real identity. How can we be happy if we don't even know for sure who we are? Most people take it for granted that we are this material body. Even people who are ostensibly religious think, "I have a soul." But this is not true; you don't have a soul-you are a soul. This subtle shift in viewpoint is the difference between material and spiritual consciousness, the difference between illusion and reality, between misery and happiness.
