The Surangama Sutra: The Origin of Demonic States, Part 7 of 7, Dec. 25, 2018

So, all these demons and ghosts, even the kings of demons, powerful in heaven, they are still imprisoned by this worldly passion and possessiveness. While you are in Samadhi, you are enjoying connecting with the Buddha Power, with your own Buddha Nature inside. You enjoy, you are pure, you are uplifted. “Therefore, they cannot affect you any more than a blowing wind can affect light, or as if a knife cannot cut through water.” Keep your mind straight, recite the Five (Holy) Names all the time when you meditate. No desire of anything; no thinking of even desiring anything; nothing; just want liberation, want to know your Buddha Nature.
