The presence of this book is a manifestation of the author's concern for preserving Batak culture which has so far escaped from anthropologists' attention, especially the spiritual culture which has many beliefs realized in the form of rituals and teachings of life to divinity and humanity wrapped in Malim Religion. These teachings are practiced by the people of Parmalim or adherents of Malim Religion today. Ritual is the realization of beliefs in the supernatural which in anthropological terms are called " religion in action ". In Malim Religion, in addition to having a number of beliefs, he also has various kinds of rituals as a manifestation of that belief in God and other supernatural beings. The types of rituals that exist in Malim Religion are mararisabtu (worship) weekly on Saturdays), martutuaek (child birth ceremonies), pasahat tondi (death ceremonies), mardebata (Debata worship ceremony), mangan na paet (bitter eating ceremonies and fasting), sipaha sada (Simarimbulubosi birth ceremony), sipaha lima (big offerings ceremony), mamasumasu (marriage ceremony), manganggir (self-purification ceremony).
