The Ten Principal Upanishads—which include the Isha, Kena, Katha, Prashna, Mundaka, Mandookya, Taittreya, Aitareya, Chhandogya, and Brihadaranyaka—are a collection of ancient Indian texts. They are considered some of the most important sources of philosophical and spiritual concepts in Hinduism, particularly regarding the relationship between the individual self (Atman) and the ultimate reality (Brahman).
This collaborative translation by Shree Purohit Swami (1882-1941), who possesses deep familiarity with Hindu scriptures and spiritual traditions, and William Butler Yeats (1865-1939), a renowned writer in modern English literature, presents a unique perspective for approaching these ancient verses. The translation aimed to make these sacred texts accessible and understandable for English-speaking readers.
