The Pure Land Sect considers the Buddha of Infinite Life, who is merely a manifestation of Śākyamuni in the Pure Land to the West, to be the lord of this world and abandons Śākyamuni, who is the real lord of this world. The Zen Sect, just like a lowly man with a little virtue despising his parents, despises the Buddha and His sūtras.
They are all confused about the Most Venerable One. It is analogous to the situation before the time of the Three Emperors, when people did not know who their fathers were and behaved like beasts and birds. Those Buddhist schools that do not know of “The Life Span of the Buddha” chapter in the Lotus Sūtra are the same as beasts and birds; they do not know the debt they owe to the Eternal Buddha. Grand Master Miao-lê declared in his Hokke gohyaku monron (500 Inquiries into the Lotus Sūtra): “Eternity in the life of the Buddha, who is our parent, has not been revealed in the pre-Lotus sūtras. (…) If one does not know the eternity in the life of his father, the Buddha, he is also confused about the Buddha land his father governs. Such a man, no matter how capable he may be, is not at all worthy of being a human.”
