Ledi Sayadaw. Ledi Sayadaw of Burma (1846-1923) was one of the greatest
scholar-monks and meditation masters of the Theravada tradition in recent
times. He was the author of over seventy manuals on different aspects of
Theravada Buddhism, including philosophy, ethics, meditation practice, and
Pali grammar. His tika created a sensation in the field of Abhidhamma
studies because he pointed out 325 places in the esteemed Vibhavini-tika
where he alleged that errors and misinterpretations had occurred, though
his criticisms also set off a reaction in defense of the older work."
