Sravaka-Buddha

Sravaka-Buddhas (Pali:Savaka-Buddhas): gain Nirvana, but attain Enlightenment by hearing the Dharma as initially taught by a Samyaksam-Buddha. After attaining enlightenment, Sravaka-Buddhas might also lead others to enlightenment, but cannot teach the Dharma in a time or world where it has been forgotten or has not been taught before, because they depend upon a tradition that stretches back to a Samyaksam-Buddha.

Sravaka-Buddhas are one of three types of Buddha. Within Mahayana Buddhism they are often referred to as Arhats.
