Although these demons possess tremendous enmity, they are in the grip of their worldly passions, while you are within wonderful enlightenment. They cannot affect you any more than a blowing wind can affect light or a knife can cut through water. You are like boiling water, while the demons are like solid ice which, in the presence of heat, soon melts away. Since they rely exclusively on spiritual powers, they are like mere guests.
When you achieve some samadhi power in your cultivation, the demon kings will be afraid and so they come to destroy it. They do not want you to have samadhi. Although these demons come to give you trouble, and although they possess tremendous enmity, much wrath, they are in the grip of their worldly passions. They are controlled by their defiled sense experiences, while you are within wonderful enlightenment. They cannot affect you any more than a blowing wind can affect light or a knife can cut through water. They cannot do anything to you, just as blowing wind could not make light move; and just as a knife, however many times it is slashed through water, could not harm the water.
You are like boiling water. In this analogy, the samadhi power from your cultivation is compared to hot water, while the demons are like solid ice. The demon kings can be compared to the solid ice of winter, which, in the presence of heat, soon melts away. As hard as the ice is, the heat of boiling water gradually causes it to melt. Since they rely exclusively on spiritual powers, they are like mere guests. All they have going for themselves is their spiritual powers, so they can never be the "host" or "master." They are merely "guests" [they cannot stay long], and they cannot succeed in their efforts to disturb you.
They can succeed in their destructiveness through your mind, which is the host of the five skandhas. If the host becomes confused, the guests will be able to do as they please.
They can succeed in their destructiveness through your mind, which is the host of the five skandhas. Basically, they cannot succeed in their destructiveness. However, if the host becomes confused—if your mind, which is the master of the five skandhas, is deluded—the guests will be able to do as they please. The guests will be able to take advantage of you. As long as you, the host, are not confused, they cannot do anything to you. Who is the host? It is your inherent nature. If your inherent nature is confused, then the demons can have their way with you. But if your inherent nature is not confused, then they are powerless to do anything.
When you are in dhyana, awakened, aware, and free of delusion, their demonic deeds can do nothing to you. As the skandhas dissolve, you enter the light. All those deviant hordes depend upon dark energy. Since light can destroy darkness, they would be destroyed if they drew near you. How could they dare linger and try to disrupt your dhyana-samadhi?
When you are in dhyana, when you have stilled your thoughts and attained the proper concentration of samadhi, you are awakened, aware, and free of delusion. Their demonic deeds can do nothing to you. The demons won't be able to trouble you with their tactics. As the skandhas dissolve, you enter the light. Demons belong to the darkness (yin), and the darkness can be dispelled. It is as if the demons were ice and you were hot water. The darkness is dispelled like ice dissolving in hot water. The fire of your wisdom is bright, so you enter the light.
All those deviant hordes of demons, externalists, goblins, ghosts, and monsters depend upon dark energy. All their tactics depend on a dark, dismal energy. Since light can destroy darkness, if you have true samadhi and wisdom, your wisdom light will shine forth and dispel the darkness.
2. The Venerable Master's explanation in January 1983
Skandha-demons are not limited to fifty kinds; there may be five hundred, five thousand, fifty thousand, or even five hundred thousand kinds. Each kind can further be divided into ten kinds. If analyzed in detail, there are thousands upon tens of thousands of kinds. In general, what is a skandha-demon? Basically it's nothing but a mass of yin energy, which comes from our yin thoughts. Yin thoughts include thoughts of greed, anger, and stupidity. They give rise to the skandhas of form, feeling, thought, formations, and consciousness; and in each of these skandhas, all kinds of yin phenomena are produced. These yin phenomena naturally appear when your skill reaches a certain level. If your skill hasn't reached that level, then you won't encounter these skandha-demons, even if you want to. They manifest only when your skill has reached that level. Don't worry when they appear. There's no need to fear being possessed by demons.
When these yin phenomena appear, you should remain calm, as if they didn't exist. See them as if not seeing them; hear them as if not hearing them; and smell them without perceiving their smell. If you don't enter into sights, sounds, smells, tastes, tangible objects, and dharmas, then the skandha-demons will not be able to do anything to you. If you are without greed, anger, and stupidity, then you will subdue these skandha-demons. If you do not have the faults of being selfish, wanting personal profit, seeking, being greedy, or contending, then no demon will be able to do anything to you.
