Another example of slandering the Lotus Sūtra is treating the Lotus Sūtra as equal to the pre-Lotus sūtras and regarding the doctrine of “achieving Buddhahood through a minor act of merit” preached in the Lotus Sūtra, chapter 2, on the “Expedients” as a mere expedient means of encouraging idlers. Therefore, Grand Master T’ien-t’ai declares in his Words and Phrases of the Lotus Sūtra, fascicle 5, “If a person does not believe in the attainment of Buddhahood through a minor act of merit, he immediately destroys all the seeds for attaining Buddhahood in this world.” Grand Master Miao-lê explains further in his Annotations on the Words and Phrases of the Lotus Sūtra, fascicle 5, “This Lotus Sūtra elucidates that all those in the six realms of the unenlightened possess the seeds for becoming a Buddha. One who slanders this sūtra, therefore, destroys all the seeds for attaining Buddhahood.”
