Roger Jackson provides accurate, accessible translations of three classics of medieval Indian Buddhist mysticism: the "couplet-treasuries" of the great tantric masters Saraha, Kanha, and Tilopa. Since their composition around 1000 CE, these poems have exerted a powerful influence on spiritual life, as well as poetry and song, in India, Nepal, and Tibet. Jackson's fresh translations allow the poetry to shine through, capturing the sense and spirit of the poems in the original. Jackson offers a thorough introduction that deftly summarizes the latest scholarship, situating the poems in their historical context and making them accessible not only to scholars but also to students and practitioners.
