Pacceka-Buddha
pacceka-buddha：an 'Independently Enlightened One'； or Separately or Individually （=pacceka） Enlightened One （renderings by 'Silent' or 'Private Buddha' are not very apt）．This is a term for an Arahat （s．ariya-puggala） who has realized Nibbāna without having heard the Buddha's doctrine from others．He comprehends the 4 Noble Truths individually （pacceka），independent of any teacher，by his own effort．He has，however，not the capacity to proclaim the Teaching effectively to others，and therefore does not become a 'Teacher of Gods and Men'，a Perfect or Universal Buddha （sammā-sambuddha ）．- Paccekabuddhas are described as frugal of speech，cherishing solitude．According to tradition，they do not arise while the Teaching of a Perfect Buddha is known； but for achieving their rank after many aeons of effort，they have to utter an aspiration before a Perfect Buddha．
Canonical references are few； Pug．29 （defin．）； A．II，56； in M．116，names of many Paccekabuddhas are given； in D．16 they are said to be worthy of a Thūpa （dagoba）； the Treasure-Store Sutta （Nidhikhandha Sutta，Khp．） mentions pacceka-bodhi； the C．Nidd．ascribes to individual Paccekabuddhas the verses of the Rhinoceros Sutta （Khaggavisāna Sutta，Sn．） - See bodhi．
