論。二者不為至所能恐怖　釋曰。由修三昧。正智相應。知境本空。知心無念。不為魔等現形恐怖。又諸魔者樂生死。此能不怖而成菩薩。

[Treatise:] Second, they cannot be terrified by [any māras or evil ghosts].
[Commentary:] Through cultivating samādhi, one corresponds with correct cognition; knowing that the object is fundamentally empty and knowing that the mind is devoid of thoughts, one cannot be terrified by māras or others manifesting forms. Furthermore, māras delight in saṃsāra; this [practitioner] can remain unfrightened and become a bodhisattva.
