Books that are essentially Hindu will focus on the worship and the wisdom of this very ancient religion. The main texts were written in Sanskrit and the Vedas meaning “truth” form the essential foundation of the Hindu belief system.
The Vedas contemplate a series of rituals, precepts, myths and chants that were originally transmitted orally. Later, these would be written to be used in rituals headed by the ancient priests. See: https://www.lifepersona.com/hindu-literature-origins-authors-and-most-important-characteristics
We try to include books from most traditions. Some of our Eastern Philosophy might also be found under New Age and Spirituality unless it is traditional Hinduism.
