This book is based on the tradition and ritual of ancient India. As time passes some of the Indian rituals and traditions were turned in superstition. So nowadays nobody knows the exact reason behind the popular traditions. We are following the traditions blindly and that is the only reason it becomes the superstition. So, in this book I tried to explain the scientific reason and logic behind the ancient Indian traditions and superstitions. My idea for writing this book is to stop blindly followed superstitions. If we want to make India advance, we have to stop our next generation from blindly following superstitions. We should accept the scientific approach instead of accepting superstitions. All the traditions and superstitions are impossible to cover in this book so I tried to cover well-known superstitions and traditions with their possible scientific reason.
