A Hinayana practitioner that strives toward liberation as an arhat based on listening to the teachings of the Buddha. Literally, "listeners" to Buddha's teachings - practitioners of the Hinayana vehicle who, motivated by renunciation, strive to attain liberation from uncontrollably recurring rebirth (samsara) and to become an arhat (liberated being) of either the shravaka or pratyekabuddha class. They practice, based on having listened to Buddha's teachings. Some translators render the term as "hearer."
J Hopkins: Hearer.
