Day 22 covers all of Chapter 17, The Variety of Merits.
“Ajita! Anyone who, after hearing this sūtra, keeps or copies it or causes others to copy it after my extinction, should be considered to have already built many hundreds of thousands of billions of monasteries, that is to say, innumerable monasteries, each of which was installed with thirty-two beautiful halls made of red candana, eight times as tall as the tala-tree, and spacious enough to accommodate one hundred thousand bhikṣus. He also should be considered to have already furnished [those monasteries] with gardens, forests, pools for bathing, promenades, and caves for the practice of dhyāna, and filled [those monasteries] with clothing, food, drink, bedding, medicine, and things for amusements, and offered [those monasteries] to me and to the Saṃgha of bhikṣus in my presence. Therefore, I say, ‘Anyone who keeps, reads or recites this sūtra, expounds it to others, copies it, causes others to copy it, or makes offerings to a copy of it after my extinction, need not build a stupa or a monastery, or make offering to the Saṃgha.’ Needless to say, anyone who not only keeps this sūtra but also gives alms, observe the precepts, practices patience, makes endeavors, concentrates his mind, and seeks wisdom, will be able to obtain the most excellent and innumerable merits. His merits will be as limitless as the sky is in the east, west, south, north, the four intermediate quarters, the zenith, and the nadir. These innumerable merits of his will help him obtain the knowledge of the equality and differences of all things.
