大毘盧遮那成佛經疏 2.67

2.67

第三十八「云何烏心？謂一切處驚怖思念」者，如烏鳥，若人善心附近惠養，或時伺求其便，俱生猜畏之心，一切時性常如是。此心亦爾，雖善友欲為饒益，及陷誤之者，一概猜阻而懷疑懼。乃至持戒修善時，亦於生死懷驚怖心。若覺知已，當修安定無畏心，是彼對治。

The thirty-eighth: "What is the crow mind? It is thinking with terror in all situations." Just as a crow, whether someone approaches with kind intentions to feed it or waits to exploit it, conceives suspicion and fear in both cases, its nature being constantly like this at all times; this mind is also like this: whether a good friend wishes to benefit it or someone seeks to ensnare it, it indiscriminately harbors suspicion, hesitation, doubt, and fear. Even when upholding precepts and cultivating good, it harbors terror toward saṃsāra. When one realizes this, cultivating a calm, stable, and fearless mind serves as its antidote.
