[29] Then the Blessed One, having dressed in the morning and taking his bowl and robe, with the Venerable Yasa as his attendant ascetic, approached the residence of the merchant householder; having approached, he sat down on the seat that had been prepared. Then the mother and the former wife of the Venerable Yasa approached the Blessed One; having approached and paid homage to the Blessed One, they sat down to one side. The Blessed One gave them a progressive discourse (anupubbikathā), that is: talk on giving, talk on virtue, talk on the heavens; he made known the danger, the degradation, and the defilement of sensual pleasures, and the benefit of renunciation. When the Blessed One knew that their minds were ready, malleable, free from the hindrances (nīvaraṇa), uplifted, and confident, then he made known that Dhamma teaching which the Buddhas have themselves exalted: suffering (dukkha), origin, cessation, path. Just as a clean cloth free from stains would take the dye evenly, even so, while they sat in that very seat, there arose in them the stainless, immaculate eye of Dhamma: "Whatever is subject to origination, all that is subject to cessation."
Having seen the Dhamma, attained the Dhamma, understood the Dhamma, fathomed the Dhamma, having crossed over doubt (vicikicchā), with perplexity gone, having attained self-confidence, independent of others in the Teacher's dispensation, they said this to the Blessed One: "Excellent, venerable sir! Excellent, venerable sir! Just as, venerable sir, one might set upright what has been overturned, or uncover what has been concealed, or point out the path to one who is lost, or hold up an oil lamp in the darkness so that those with eyes may see forms — even so has the Dhamma been made known by the Blessed One in many ways. We, venerable sir, go to the Blessed One for refuge, and to the Dhamma, and to the Saṅgha of bhikkhus. May the Blessed One remember us as female lay followers (upāsikā) who from this day forth have gone for refuge for as long as life lasts." And they were the first female lay followers in the world by the threefold declaration (tevācikā).
Then the mother and the father and the former wife of the Venerable Yasa, having with their own hands served and satisfied the Blessed One and the Venerable Yasa with excellent hard and soft food, when the Blessed One had finished eating and had withdrawn his hand from the bowl, sat down to one side. Then the Blessed One, having instructed, inspired, roused, and gladdened the mother and the father and the former wife of the Venerable Yasa with a Dhamma talk, rose from his seat and departed.
