大毘盧遮那成佛經疏 2.45

2.45

Sixteenth: regarding "What is the asura mind? It means delighting in dwelling in saṃsāra": 'a' means non, and 'sura' means deva; because their karmic retribution resembles that of devas, but their actions and dwelling places are different, they are named thus. This [person] knows that there is the benefit of liberation, yet deeply delights in the happiness of the retribution of saṃsāra and is unable to advance. If a practitioner has this appearance, one should know that it is called the asura mind. It is also because of having previously been born in this destiny in past lives that one has this habit. Contemplating impermanence, suffering, and the like is its antidote.
