The “Teacher of the Dharma” chapter of the Lotus Sūtra, fascicle 4, preaches, “Among the sūtras which had been preached, are now being preached, and will be preached, this Lotus Sūtra is the most difficult to embrace and perceive.” The “Peaceful Practices” chapter also states that the Lotus Sūtra is above all other sūtras. The “Medicine King Bodhisattva” chapter enumerates the ten kinds of simile to confirm the superiority of the Lotus Sūtra among all the scriptures of Buddhism. Beside the Lotus Sūtra such sūtras as the Flower Garland Sūtra, the Hōdō Sūtras, the Wisdom Sūtra, the Revealing the Profound and Secret Sūtra, the Great Cloud Sūtra, the Sūtra of Mystic Glorification, and the Sūtra of the Golden Splendor speak of the comparative superiority of sūtras. However, they claim to be supreme against Hinayāna sūtras, call the Principle of the Middle Way superior to the truth of emptiness and that of temporariness, or claim to be supreme for simply being able to explain finger signs (mudrā) and mantras. Though they make various claims to be supreme, their claims of superiority have never been as absolute as that of the Lotus Sūtra, which is said to be superior to all the sūtras preached in the past, present, and future.
