Majma-ul-Bahrain (Hindi: मज्म 'उल बह् रैन', Urdu: مجمع البحرین‎, "The Confluence of the Two Seas") is a book on comparative religion authored by Dara Shukoh. Majma Al Bahrayn, or ‘ the Mingling of the Two Oceans,’ is the fifth work of Dara Shikuh which he completed in 1065 A.H., namely, when he was forty-two years old. It was devoted to a revelation of the mystical and pluralistic affinities between Sufic and Vedantic speculation. It was one of the earliest works to explore both the diversity of religions and a unity of Islam and Hinduism and other religions. The book was authored as a short treatise in Persian in 1654–55. Its Hindi version is called Samudra Sangam Grantha.
