注大乘入楞伽經 5.251

5.251

上說行內五無間不入地獄，得現證實法，恐人聞此謂行外五無間亦不入地獄，故次明行外五無間得地獄苦，令聞是義不生疑惑也。

The preceding explained that committing the internal five deeds of immediate retribution does not lead to entering hell, but rather to realizing and witnessing true reality. Fearing that people hearing this might think that committing the external five deeds of immediate retribution also does not lead to entering hell, it next explains that committing the external five deeds of immediate retribution leads to the suffering of hell, so that those hearing this meaning will not harbor doubts.
