Swami Tirtha (1959–) is a monk of the bhakti school of Hinduism. His books and stud­ies reveal the beauty of the spir­itu­al paths. The Black Book dis­tils his many dec­ades of exper­i­ence as a research­er and lec­turer, and with the help of uni­ver­sal wis­dom it leads to a fuller and finer life.
