The collection of texts centers on an alternative history of Sri Lanka and the origins of Buddhism, positing that Sri Lanka, referred to as Atalanka or the mountain peak of the lost continent Atlantis/Kumari Kandam, was the true cradle of both a powerful ancient civilization and the Buddha. The source argues that a seven-year rain event submerged Atalanka, forcing many inhabitants (the Ra Vana or Sun Lineage) to migrate and found civilizations like Egypt and Mesopotamia, while the remaining mountain people, the Helayo, developed a culture of introspection that led to the emergence of Gautama Buddha.
