A "holy book" is a text that is considered sacred and authoritative in a particular religion. These books often contain teachings, laws, stories, and guidelines that followers believe to be divinely inspired. Examples include the Bible in Christianity, the Quran in Islam, and the Vedas in Hinduism. Holy books serve as a foundation for the beliefs and practices of their respective faiths. They are often used in worship, study, and moral guidance. Many believers regard these texts as a way to connect with the divine and understand their purpose in life.
