次十二入。而辨十八界者。以惑者迷於名色俱重故。開色為十。離名作八。合為十八界也。通名界者。以界別為義。此十八法各有別體。義無渾濫。故通受界名也。
Next, the twelve sense fields are further distinguished into eighteen realms. This is because those who are confused are deeply entangled with both material form and mental phenomena. Therefore, material form is divided into ten, and mental phenomena are separated into eight, making a total of eighteen realms.
The general term "realm" means differentiation. Each of these eighteen dharmas has its own distinct nature, and their meanings do not mix or become confused. Therefore, they are collectively called "realms."
內六根界 此具如前明。內六根入中分別其相。乃更加以界之名義者。欲使修觀之徒推析無謬。不滯十六知見之妄計也。
外六塵界 此具如前。外六塵入中分別其相。乃更加以界之名義者。意同六根。中立界名。
六識界者。若根塵相對即有識生。識以識別為義。識依於根。能識別於塵。故此六通名識也。若了識從緣生。豈計有神使知謬取也。
一眼識界 眼根若對色塵。即生眼識。眼識生時。即識色塵。故名眼識界也。
二耳識界 耳根若對聲塵。即生耳識。耳識生時。即識聲塵。故名耳識界也。
三鼻識界 鼻根若對香塵。即生鼻識。鼻識生時。即識香塵。故名鼻識界也。
四舌識界 舌根若對味塵。即生舌識。舌識生時。即識味塵。故名舌識界也。
五身識界 身根若對觸塵。即生身識。身識生時。即識觸塵。故名身識界也。
六意識界 五識生已即滅。意為意識。此意識續生。意識生時。即識法塵。若五識能生意識。即以前五識為根。後意識為意識。此意識滅次識續生。是則前意識生後意識。如是亦脫傳受根識之名。皆以能生為根。所生為識。今說所生之識。為意識界也。
