From the Manjusri-pariprccha-sutra, Translated by Paul Swanson (published in Vol. 3 of the MohoChihkuan, Clear Serenity, Quiet Insight:
There's some anachronistic and socially inapplicable advice there, but the gist is clear enough.The Buddha said to Manjusri, "If you are able to singularly by mindful of the Tathagata's ten titles, the Buddha is constantly present and never perishes [for] this person. You are also able to hear all the teachings of the buddhas, and see these Buddhas, and see these Buddhas appearing in front of the four assmeblies [of monks, nuns, laymen, and laywomen], and can increase your life span and never suffer from disease. What are these ten titles? They are:
1. Thus-come One (tathagata)
2. One Who Deserves Honor or Offerings (arhat)
3. One Who Has Realized Complete Awakening (samyak-sambuddha)
4. One Who Is Fully Proficient in Awakening and Practice (vidya-carana-sampanna)
5. Well-Gone One (sugata)
6. One Who Understands the World (lokavid)
7. Supreme One (annuttara)
8. Tamer of Beings (purusadam-ya-sarathi
9. Teacher of Divine and Human Beings (sasta devamanusysnam)
10. Buddha World Honored One (buddha bhagavat)
"Manjusri, one who is mindful of these ten titles should first be mindful of the Buddha's [physical] body endowed with the major and minor marks, and also mindful of the Dharma body, whose life is inexhaustible. You should have these thoughts: the Buddha does not have a [substantial] physical body; the Buddha is the Dharma body. You should diligently and adamantly perceive the Buddha as [empty] like space. Through [experiencing] the bliss of space, you know the meaning of all dharmas...
How are lay people able to cultivate this samadhi? With faith in karmic recompense, abandon all [earthly] possessions, take refuge in the three treasures [of Buddha, Dharma, and Sangha], accept and keep the five [major] precepts [of no killing, no stealing, no sexual impropriety, no lying, and no imbibing of intoxicants]; do not be petty, destructive, impure, or deficient; accept the path of the ten good deeds that leads to arousing all good things; cultivate pure deeds (brahma-carya) and smash the five desires [of the five senses]; do not arouse jealousy and do not be passionately attached to your wife and children; constantly find pleasure in leaving the home and accepting the eight precepts [that a lay person observes for a day and a night at a time; that is, the five major precepts plus no wearing ornaments or taking part in dancing or music, no sleeping in a high and comfortable bed, and no eating after noon]; constantly dwell in the monks' quarters with a humble heart; always have respect for the home-departed; do not be stingy but always take pleasure in being transformed; think fondly of and respect the monks, masters, and preachers of the Dharma; let your attitude toward parents and teachers ["good friends"] be like that of your thoughts for the Buddha-rely on your parents and teachers, so that you can dwell in a quiet and isolated place. In this way lay people can cultivate this samadhi...
