「大富長者」下，第三、合譬。但合五譬：一、合初為父子譬；二、合中途相失譬；三、合誘引還家譬；四、合付財密化譬；五、合委囑家業譬。所以但合五者，初為父子是結緣之始故須合之；背化流浪生死，蓋是中途相失時亦須合也；後之三譬是釋迦一期出世大小顯密始終教門亦須合之。餘譬說已顯不待合也。

From "The wealthy elder" onward: third, matching the parables. It matches only five parables: first, matching the parable of originally being father and son; second, matching the parable of separation mid-journey; third, matching the parable of enticing him to return home; fourth, matching the parable of secretly converting through the entrustment of wealth; fifth, matching the parable of entrusting the family estate. The reason it matches only five is that originally being father and son is the inception of forming the connection, so it must be matched; turning against conversion and wandering through birth and death is the time of separation mid-journey, so it must also be matched; the latter three parables are Śākyamuni's lifetime appearance in the world, the beginning-to-end teaching methods of greater and lesser, manifest and secret, so they must also be matched. The other parables have already been explained clearly and do not await matching.
