Nandiya Sutta: To Nandiya
On one occasion the Blessed One was staying among the Sakyans near Kapilavatthu in Nigrodha's Park. Then Nandiya the Sakyan went to the Blessed One and, on arrival, having bowed down to him, sat to one side. As he was sitting there he said to the Blessed One, "Lord, the disciple of the noble ones in whom the factors of stream entry are altogether & in every way lacking: Is he called a disciple of the noble ones who lives heedlessly?"
"Nandiya, the person in whom the factors of stream entry are altogether & in every way lacking I call an outsider, one who stands in the faction of the run-of-the-mill. But as to how a disciple of the noble ones lives heedlessly and heedfully, listen well and pay attention, I will speak"
"As you say, lord," Nandiya the Sakyan responded.
The Blessed One said, "And how, Nandiya, does a disciple of the noble ones live heedlessly? There is the case where a disciple of the noble ones is endowed with verified confidence in the Awakened One: 'Indeed, the Blessed One is worthy and rightly self-awakened, consummate in knowledge & conduct, well-gone, an expert with regard to the world, unexcelled as a trainer for those people fit to be tamed, the Teacher of divine & human beings, awakened, blessed.' Content with that verified confidence in the Awakened One, he does not exert himself further in solitude by day or seclusion by night. For him, living thus heedlessly, there is no joy. There being no joy, there is no rapture. There being no rapture, there is no serenity. There being no serenity, he dwells in pain. When pained, the mind does not become centered. When the mind is uncentered, phenomena do not become manifest. When phenomena are not manifest, he is reckoned simply as one who dwells heedlessly.
"Furthermore, the disciple of the noble ones is endowed with verified confidence in the Dhamma: 'The Dhamma is well-expounded by the Blessed One, to be seen here & now, timeless, inviting verification, pertinent, to be realized by the wise for themselves.' Content with that verified confidence in the Dhamma, he does not exert himself further in solitude by day or seclusion by night. For him, living thus heedlessly, there is no joy. There being no joy, there is no rapture. There being no rapture, there is no serenity. There being no serenity, he dwells in pain. When pained, the mind does not become centered. When the mind is uncentered, phenomena do not become manifest. When phenomena are not manifest, he is reckoned simply as one who dwells heedlessly.
"Furthermore, the disciple of the noble ones is endowed with verified confidence in the 'The Sangha of the Blessed One's disciples who have practiced well... who have practiced straight-forwardly... who have practiced methodically... who have practiced masterfully — in other words, the four types of noble disciples when taken as pairs, the eight when taken as individual types — they are the Sangha of the Blessed One's disciples: worthy of gifts, worthy of hospitality, worthy of offerings, worthy of respect, the incomparable field of merit for the world.' Content with that verified confidence in the Sangha, he does not exert himself further in solitude by day or seclusion by night. For him, living thus heedlessly, there is no joy. There being no joy, there is no rapture. There being no rapture, there is no serenity. There being no serenity, he dwells in pain. When pained, the mind does not become centered. When the mind is uncentered, phenomena do not become manifest. When phenomena are not manifest, he is reckoned simply as one who dwells heedlessly.
"Furthermore, the disciple of the noble ones is endowed with virtues that are appealing to the noble ones: untorn, unbroken, unspotted, unsplattered, liberating, praised by the wise, untarnished, leading to concentration. Content with those virtues pleasing to the noble ones, he does not exert himself further in solitude by day or seclusion by night. For him, living thus heedlessly, there is no joy. There being no joy, there is no rapture. There being no rapture, there is no serenity. There being no serenity, he dwells in pain. When pained, the mind does not become centered. When the mind is uncentered, phenomena do not become manifest. When phenomena are not manifest, he is reckoned simply as one who dwells heedlessly.
"This is how a disciple of the noble ones lives heedlessly.
"And how, Nandiya, does a disciple of the noble ones live heedfully? There is the case where a disciple of the noble ones is endowed with verified confidence in the Awakened One... Not content with that verified confidence in the Awakened One, he exerts himself further in solitude by day or seclusion by night. For him, living thus heedfully, joy arises. In one who has joy, rapture arises. In one who has rapture, the body becomes serene. When the body is serene, one feels pleasure. Feeling pleasure, the mind becomes centered. When the mind is centered, phenomena become manifest. When phenomena are manifest, he is reckoned as one who dwells heedfully.

That one needs to spend long time, being very discerning, observes... to know ones qualities?
[Kapadika Bharadvaja:] "To what extent is there an awakening to the truth? To what extent does one awaken to the truth? We ask Master Gotama about awakening to the truth."
[The Buddha:] "There is the case, Bharadvaja, where a monk lives in dependence on a certain village or town. Then a householder or householder's son goes to him and observes him with regard to three mental qualities — qualities based on greed, qualities based on aversion, qualities based on delusion: 'Are there in this venerable one any such qualities based on greed that, with his mind overcome by these qualities, he might say, "I know," while not knowing, or say, "I see," while not seeing; or that he might urge another to act in a way that was for his/her long-term harm & pain?' As he observes him, he comes to know, 'There are in this venerable one no such qualities based on greed... His bodily behavior & verbal behavior are those of one not greedy. And the Dhamma he teaches is deep, hard to see, hard to realize, tranquil, refined, beyond the scope of conjecture, subtle, to-be-experienced by the wise. This Dhamma can't easily be taught by a person who's greedy.
"When, on observing that the monk is purified with regard to qualities based on greed, he next observes him with regard to qualities based on aversion... based on delusion: 'Are there in this venerable one any such qualities based on delusion that, with his mind overcome by these qualities, he might say, "I know," while not knowing, or say, "I see," while not seeing; or that he might urge another to act in a way that was for his/her long-term harm & pain?' As he observes him, he comes to know, 'There are in this venerable one no such qualities based on delusion... His bodily behavior & verbal behavior are those of one not deluded. And the Dhamma he teaches is deep, hard to see, hard to realize, tranquil, refined, beyond the scope of conjecture, subtle, to-be-experienced by the wise. This Dhamma can't easily be taught by a person who's deluded.
"When, on observing that the monk is purified with regard to qualities based on delusion, he places conviction in him. With the arising of conviction, he visits him & grows close to him. Growing close to him, he lends ear. Lending ear, he hears the Dhamma. Hearing the Dhamma, he remembers it. Remembering it, he penetrates the meaning of those dhammas. Penetrating the meaning, he comes to an agreement through pondering those dhammas. There being an agreement through pondering those dhammas, desire arises. With the arising of desire, he becomes willing. Willing, he contemplates [lit: "weighs," "compares"]. Contemplating, he makes an exertion. Exerting himself, he both realizes the ultimate meaning of the truth with his body and sees by penetrating it with discernment.
"To this extent, Bharadvaja, there is an awakening to the truth. To this extent one awakens to the truth. I describe this as an awakening to the truth. But it is not yet the final attainment of the truth."
[Kapadika Bharadvaja:] "Yes, Master Gotama, to this extent there is an awakening to the truth. To this extent one awakens to the truth. We regard this as an awakening to the truth. But to what extent is there the final attainment of the truth? To what extent does one finally attain the truth? We ask Master Gotama about the final attainment of the truth."
[Buddha:] "The cultivation, development, & pursuit of those very same qualities: to this extent, Bharadvaja, there is the final attainment of the truth. To this extent one finally attains the truth. I describe this as the final attainment of the truth."

If searching for another house before leaving it, how could one ever find out?
It's not so easy to find refuge.
But one thing, maybe of help: all eight persons having overcome macchariya . And to meet them, see them, one has to overcome it by oneself first, by leaving external security, ones palace.
