Is the channeled material given by [name withheld] described as coming from an Archangel reliable, and what was the true source of this entity?

This was material conveyed by an Anunnaki psychic. It is much like almost all such channelings in that regard—a useful, if incomplete, compendium of divine truths that are compact and contain the essence of many useful types of knowledge, but will not delve deeply and will not give ultimate answers for the growth of humanity, and certainly not enough information to arm people against an outside foe and help them to surmount high-level difficulty. There is little insight about healing. It is well and good to discuss the ideals, to discuss how things need to be, to discuss the examples of how things can go awry in human thinking and the use of their emotions. But it is quite another to offer a therapeutic answer or intervention to undo distortions that create unhealthy patterns of thought and inner beliefs that have become twisted through the traumas of life to take a person away from alignment with the light and love of Creator. In this, the channeled material falls well short. So it appears helpful on the surface, but is deliberately designed to dull the thinking and create the impression of having all necessary truth, but without truly delivering the goods, so to speak.
