Day 22 covers all of Chapter 17, The Variety of Merits.

Having last month covered the merits of those who do not speak ill of this sutra but rejoice at hearing it after my extinction, it’s on to the merits of those who read, recite or keep this sutra, expound it to others, copies it, or causes others to copy it.

Ajita! Anyone who, after hearing this sutra, 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 bhiksus. He also should be considered to have already furnished [those monasteries] with gardens, forests, pools for bathing, promenades, and caves for the practice of dhyana, and filled [those monasteries] with clothing, food, drink, bedding, medicine, and things for amusements, and offered [those monasteries] to me and to the Samgha of bhiksus in my presence. Therefore, I say, ‘Anyone who keeps, reads or recites this sutra, 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 Samgha.’ Needless to say, anyone who not only keeps this sutra but also gives alms, observes 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.

Anyone who reads, recites or keeps this sutra, expounds it to others, copies it, or causes others to copy it [in my lifetime,] should be considered to have already built stupas and monasteries, made offerings to the Samgha of Sravakas, praised them, praised Bodhisattvas for their merits by hundreds of thousands of billions of ways of praising, expounded this Sutra of the Lotus Flower of the Wonderful Dharma to others with various stories of previous lives according to the meanings of it, observed the precepts without fallacy, lived with gentle persons, practiced patience, refrained from anger, become resolute in mind, preferred sitting in dhyana, practiced deep concentrations of mind, become strenuous and brave, practiced good teachings, become clever and wise, and answered questions satisfactorily. Ajita! Any good man or woman who keeps, reads, or recites this sutra after my extinction, also will be able to obtain these merits. Know this! He or she should be considered to have already reached the place of enlightenment, approached Anuttara-­samyak-sambodhi, and sat under the tree of enlightenment. Ajita! Erect a stupa in the place where he or she sat, stood or walked! All gods and men should make offerings to that stupa just as they do to the stupa of a Buddha.

He or she should be considered to have already reached the place of enlightenment, approached Anuttara-samyak-saṃbodhi, and sat under the tree of enlightenment. Ajita!
