In the first century C.E., an eminent Buddhist scholar named Upatissa wrote the Vimuttimagga (The Path of Freedom), in which he summarized the Buddha’s teachings on meditation. In the fifth century C.E., another great Buddhist scholar, named Buddhaghosa, covered the same ground in a second scholastic thesis, the Visuddhimagga (The Path of Purification), which remains the standard text on meditation today.
