Can a person’s spirit team block the energy of a psychic attack?

This cannot be done in a practical way because of free will and free agency. This is the central dilemma we are all working through to see what can be learned from reckoning with the rise of evil corrupting things in so many ways and creating extra burdens and roadblocks to improve things. That is the reason why things are so challenging, it is not that the system is flawed, it is that the paradigm contains, inherently, many downsides, irregularities, pitfalls, and opportunities for bad things to happen so it is far from an ideal circumstance. That is all a product of consciousness gone wrong, consciousness misdirected, misapplied, and often for selfish reasons. That is all a consequence of getting out of divine alignment in the first place. So you cannot have a spirit team act as minders and keepers and attendants, let alone arbiters of what you are able to experience and what you might be shielded from. There are some things that can be done, especially when it is done by other species attacking you. But what humans do to one another is human business, first and foremost, and cannot simply be deflected. That is what the Law of Karma is there for, to see that you get a reckoning, a consequence, some kind of penalty if you make a misstep and compromise the sovereignty of someone else. So this illustrates why everyone is working behind the curve, being always in a catch-up mode, because of the very fact that things cannot be prevented through divine intervention, in most cases, unless there are special circumstances or considerations, for example, where there is much prayer work and healing underway to address someone who is harming another, and the prevention of continued harm is serving both parties in response to direct appeals for help, because there we can act in response to human intention directly, for us to be involved.
