Mysteries of life have always challenged human mind. What is this universe? How did it come into existence? Who am I? What is the purpose of human life? Does God exist? If so who created Him? These are perennial questions. Some sort of divine presence emerged as a human answer to these unintelligible riddles of our existence which were interpreted and named differently by different societies giving birth to multiple religions and scriptures. Ironically these very religions also promote blind faith and intolerance impeding human quest for the truth. In this volume I have made an attempt to rise above these narrow religious walls and rituals to explain the spiritual - a profound science that enables us to understand the power of the insensible and unintelligible. Most of these thoughts form part of the ancient Vedic writings of India. Given growing religious intolerance, mad race for consumerism, degradation of environment and ever-increasing mental stress and ailments these thought are more relevant today than ever before.
