Day 22 covers all of Chapter 17, The Variety of Merits.
“Anyone who reads, recites or keeps this sūtra, 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 Saṃgha of Śrāvakas, praised them, praised Bodhisattvas for their merits by hundreds of thousands of billions of ways of praising, expounded this Sūtra 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 dhyāna, 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 sūtra 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-saṃbodhi, 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.”
