唯識二十論述記 2.235

2.235

述曰：下以理解，此釋下句頌中「夢」字。生死之識，不稱實理，說為「虛妄」；無始已來，數數熏發，名為「串習」；蓋纏覆蔽，稱之為「惛」；毒火所煎，號之為「熱」。或復串習無明稱「惛」；聖智不生，名之為「熱」；猶如世間數習闇昧惛睡之識，名之為「夢」。生死亦爾，睡者惛熱義，夢睡心之異名，即說生死名世間爾，如經所說生死長夜。

Commentary: Below it is explained through principle; this explains the word 'dream' in the second line of the verse. Consciousness in saṃsāra does not correspond to real principle, so it is said to be 'false'; since beginningless time it has repeatedly perfumed and arisen, so it is called 'habituated'; covered and obstructed by hindrances and entanglements, it is called 'stupor'; scorched by the fire of poisons, it is designated as 'fever'. Alternatively, habituated ignorance is called 'stupor'; noble cognition not arising is called 'fever'; just as worldly consciousness repeatedly habituated in darkness and torpid sleep is called a 'dream'. Saṃsāra is also like this: 'sleep' has the meaning of stupor and fever, and 'dream' is an alternate name for the sleeping mind; that is, saṃsāra is called the world, as the sūtra speaks of the long night of saṃsāra.
