teaching of gleaning ［捃拾教］ ( kunjū-kyō): A reference to the Nirvana Sutra. According to the doctrine of the five periods and eight teachings set forth by T’ien-t’ai (538–597), the preaching of the Lotus Sutra was followed by that of the Nirvana Sutra. The T’ien-t’ai school compared the Lotus Sutra to the harvest and the Nirvana Sutra to the gleaning that comes after the harvest. That is, the Nirvana Sutra was preached to extend enlightenment to those who had been left out during the exposition of the Lotus Sutra and failed to benefit from it. Hence the Nirvana Sutra is termed the teaching of gleaning.
