Day 22 covers all of Chapter 17, The Variety of Merits.
Having last month considered the heavenly response to the description of the merits, we consider the innumerable merits earned by understanding by faith the lifespan of the Buddha.
Thereupon the Buddha said to Maitreya Bodhisattva-mahāsattva: “Ajita! Anyone who hears that my life is so long, and understands it by faith even at a moment’s thought, will be able to obtain innumerable merits. Suppose good men or women practiced [ the six pāramitās] except the prajñā- pāramitā, that is, the five pāramitās: the dāna-pāramitā, the śīla-pāramitā, the kṣānti-pāramitā, the vīrya-pāramitā, and the dhyāna-pāramitā, for eighty billion nayuta kalpas in order to attain Anuttara-samyak-saṃbodhi. These merits of the good men or women are far less than one hundredth or one thousandth of the merits of the person [who understand my longevity by faith even at a moment’s thought], or less than his merits divided by one hundred thousand billion. [The superiority of his merits to theirs] cannot be explained by any calculation or parable or simile.
It cannot be that the good man who obtained merits [by understanding my longevity by faith even at a moment’s thought] falters in walking the Way to Anuttara-samyak-saṃbodhi.”
