One Single Teaching

The first half of the Lotus Sutra (Shakumon) expounds the teaching of the One Vehicle. The several schools of Buddhism, which are divided roughly into three types (Sravaka-Vehicle, Pratyekabuddha-Vehicle, and Bodhisattva-Vehicle), are unified in the one single teaching of the One Vehicle. Since the number three represents all the various Buddhist Teachings, “three” here implies “many” or “all.”
