Can seers be tricked by other spiritual entities or other seers, such as black magicians and Anunnaki psychics? How would a seer protect themselves against that?

Such deceptions are almost universal in influencing would-be seers, those with psychic ability of all kinds, largely without their knowing it is happening. Much is done to diminish having an intuitive reach by subliminal programming done by the interlopers, to keep people dimmed down and dumbed down, both. They weaken the ability of the mind itself, let alone the higher intuitive senses, but they work avidly to diminish those with psychic ability to sideline them, disempower them, keep them in the dark, and corrupt them. This will always be engineered relentlessly, because the interlopers fear those with intuitive ability, because they know such individuals can develop the ability to learn their secrets, know what they are up to and, when they band together especially, have a mysterious ability to thwart their dark plans and machinations. They do not realize this is largely divine intervention when their plans fail to have the desired level of impact, so they assume, being nonbelievers in a higher power than themselves, there is something about human consciousness that when people band together and their minds align, mysterious things happen, but try as they might they cannot determine what is happening mechanistically, because of this blind spot of absent belief in the divine. What people need to prevent their manipulation, their distortion, their corruption, and their subjugation is to align with the Almighty in partnership and to request protection, ideally on a daily basis through prayer, and to pray also to cultivate stronger and stronger belief in us. Many have beliefs in the divine that are shaky and they harbor much doubt about the ability of themselves to receive divine assistance because they have been programmed to believe God is great and they are not. We cherish you, but you have free will so you can choose to be with us or without us and, because of the Free Will Paradigm, we must follow your lead, your instructions, your requests, and your invitations. Without those, we cannot act in your world at all. If you want safety and ask for it, we will do all we can to honor that request but that, too, will be a function of the strength of your intention, the purity of your heart, the level of your belief in us, and your belief quotient regarding your own worthiness. All of the shortcomings and impediments to divine alignment can be healed, that is why enlightenment is a healing journey, and a work in progress for everyone in the physical, because you are walking wounded.
