Preface This book is written from practical experience and for the future generation's reference. The heritage and historical buildings are significant to evident the actual history. The two primary reasons were kept in mind during the writing of this book. First, is the historical significance. Second, many self-made scholars put detriment to the Khalsa Panth history and deterring the name of the Historical places with their thoughts without any research. The history given in this book is referenced from the Khalsa Panth authenticated resources like Mahan Kosh of Bhai Kahan Singh Nabha, Suraj Parkash Granth, Prachin Panth Prakash, and the scholars of Damdami Taksal. This book aims to guide how to restore the centuries-old building with the same material in their original structure. It also explains that the ingredients used in the material are powerful and helpful in the environment for better health. The heritage and historical buildings do not need to destroy by saying that there is no way to save them. This book provides ways to keep the historically significant building to preserve them for the coming generations. These buildings provide pieces of evidence for the glory of the religions, states, and nations. The development of the Sikha Theory of Restoration, Renovation, and Reconstruction was based on the guidance from the material used during the Khalsa empires. It explains how that material is beneficial for human and environmental health, how nature made the materials for constructing the buildings, and how we can use them for a better living experience.
