The Lord Śākyamuni Buddha is the lifetime head of a Buddhist Order and guiding teacher of all living beings. The eighty thousand Buddhist teachings preached by Śākyamuni Buddha are all words of wisdom, and the 12 divisions of Mahāyāna scriptures are all true. All the scriptures of Buddhism were preached by Śākyamuni Buddha who upheld the precept of not spreading lies. Therefore, each of the teachings should not be doubted. This, however, is a generalization. If we study them thoroughly, we can perceive differences between the Mahāyāna and Hinayana, exoteric and esoteric, and provisional and true teachings, though they were all uttered from the golden mouth of Śākyamuni Buddha. Now in this Lotus Sūtra (the “Expedients” chapter) the Buddha declares, “He honestly abandons the expedient teachings and expounds only the true way; after preaching various sūtras He inevitably preaches the very true teaching in the end.” Who can doubt this?
