說無垢稱經疏 3.242

3.242

贊曰：此中一對，謂苦樂對。無間者，無間地獄，舉一極苦之處。解脫者，涅槃極樂之處。以極苦真如，入極樂真如，體一味故。舊云「以五逆相而得解脫」，應言五逆果之相入解脫之相，即真如故。

The Commentary says: Here is one pair, namely the pair of suffering and bliss. 'Avīci' refers to the Avīci hell, citing an extreme place of suffering. 'Liberation' refers to Nirvāṇa, the extreme place of bliss. By entering the tathatā of extreme bliss by means of the tathatā of extreme suffering, their nature is of one taste. The older [translation] says: 'Attaining liberation by means of the marks of the five immediate deeds'; one should rather say that the marks of the fruits of the five immediate deeds enter the marks of liberation, precisely because they are tathatā.
