大乘起信論略述 2.197

論。當念唯心至終不為惱　述曰。此略辨治也。一切諸境尚唯自心。何況坐中境非心也。是故觀察唯心之理。惱境自滅不能亂。魔境皆依動念生故。觀察唯心非彼知故。

[Treatise:] One should be mindful that [everything is] mind-only [... they will never cause harassment]. [Exposition:] This briefly discerns the remedy. All objective realms are merely one's own mind, so how could the realms [appearing] during meditation not be mind? Therefore, contemplating the principle of mind-only, the harassing objects naturally perish and cannot cause disturbance. Demonic realms all arise relying on stirring thoughts; because one contemplates mind-only, they are not [independently] known by those [beings].
