Day 21 covers all of Chapter 16, The Duration of the Life of the Tathāgata.
Having last month considered Śākyamuni’s various activities during his lifetime, we consider purpose of the sūtras expounded to this point.
“Good men! All the sūtras that I expounded [hitherto] were for the purpose of saving all living beings. I told the stories of my previous lives [in some sūtras,] and the stories of the previous lives of other Buddhas [in other sūtras]. I showed my replicas [in some sūtras,] and my transformations [in other sūtras]. I described my deeds [in some sūtras,] and the deeds of others [in other sūtras]. All that I say is true, not false, because I see the triple world as it is. I see that the triple world is the world in which the living beings have neither birth nor death, that is to say, do not appear or disappear, that it is the world in which I do not appear or from which l do not disappear, that it is not real or unreal, and that it is not as it seems or as it does not seem. I do not see the triple world in the same way as [the living beings of] the triple world do. I see all this clearly and infallibly. The living beings are various in their natures, desires, deeds, thoughts and opinions. Therefore, I expounded the dharma with various stories of previous lives, with various parables, similes and discourses, in order to cause all living beings to plant the roots of good. l have never stopped doing what I should do. As I said before, it is very long since I became the Buddha. The duration of my life is innumerable, asaṃkhya kalpas. I am always here. I shall never pass away.
This portion of Chapter 16 is used by Nichiren to explore the manifestation of Śākyamuni’s powers:
It is preached in the “Life Span of the Buddha” chapter of the Lotus Sūtra, “The scriptures that I, the Buddha, expound are all for the purpose of emancipating all living beings. For this purpose I guide them in various ways, sometimes speaking of myself, sometime of others. Sometimes I present myself, sometimes others. Sometimes I show my own actions, sometimes those of others.”
Accordingly, who among the great beings – Zentoku Buddha of the World Without Worry to the east; the Great Sun Buddha in the center of the universe; various Buddhas in the worlds throughout the universe; the past seven Buddhas who appeared in this world; various Buddhas in the past, present, and future; the direct disciples of the Original Buddha who emerged from the earth such as Bodhisattva Superior Practice; bodhisattvas of theoretical teachings, such as Mañjuśrī, Śrāvaka disciples such as Śāriputra, the King of the Mahābrahman Heaven who controls the triple world; the King of Devils who lives in the Sixth Heaven in the realm of desire; Indra who controls the Trāyastriṃsá Heaven; or Sun Deity, Moon Deity, Deity of the Stars, innumerable stars such as the Great Bear, twenty-eight stars, Five Stars, Seven Stars and 84,000 Stars; those who occupy the headship of various places throughout the world such as the King of asura demons, god of the heavens, god of the earth, god of the mountains, god of the ocean, god of the house, and god of the village – is not a manifestation of the Lord Teacher Śākyamuni Buddha?
