I think unless as a temporary solution those medications are bad, 1. because AFAIK they suspend the patient's imagination, 2. because they can't stop taking them easily without possible side effects and 3. because if they're being attacked by someone from other dimension, the attacks won't stop. The only difference is the patient doesn't realize about them. Although the beings might stop harassing if they notice the patient has no perception of them. But closing the chakras or dulling the brain with pills are no decent solutions. It's best to go to the root of the problem, otherwise you're just treating the symptoms, which will come back without medication. And probably the dreaded day will come when no medication will be good enough.
Both are related. The external spiritual battle is a reflection of an internal one; of a "behavioral issue". If the patient is being attacked by someone, physical or not, it means he or she is attracting enemies for a hidden want for death or sickness. Does he or she wants to be healed on one hand but on the other unknowingly wants to suffer and die because of a lack of self-esteem, guilt or lack of love? Or wants to be sick to be taken care of, to feel loved? What's the real reason behind a disease, mental or not? Louise Hay has a very good book "You can heal your life" on that subject.
A few months ago I had a vision in trance of the horned god and he said my nightmares with "demons" were due to accumulated anger that I couldn't release. So that anger turned against myself. That attracted evil beings that attacked me in my dreams (real astral beings or not, they bothered me anyway). Nightmares diminished a lot once I intended to control my rage. The horned god suggested me to imagine my rage as a black smoke getting into a bottle and using that energy only when it's necessary. Even if you don't believe in the horned god, it's a good idea!
In any case it was too much coincidence; the prayer I've mentioned worked every time! It doesn't even has to be said out loud. Because it's not an external god that I'm asking that may or may not pay attention, but my own higher self.
And it's not the only prayer you can use though. You could repeat 3 times "I light this candle for John Smith" and light a white candle. That's also effective. What matters is that you use the candle light as a symbol of the energy you emit from your true self.
If the patient is Christian you could even recommend him or her to ask Jesus the protection of archangel Michael, 3 times, with his own words. Every religion has methods that work. I currently say "Internal dragon, protect me in a good way." 3 times. The dragon is a symbol of internal power.
Anyway praying is good but it's a little like providing a medication. Sooner or later the patient himself will have to be in charge of improving his own mind; in emitting his own light. You may give someone a push towards healing, but you can't help someone who doesn't really want to be helped. Maybe there's a deep reason why they don't want any help.
OK I sent you light a few minutes ago, but you don't need me to pray for you, really. You could release light from your own self by repeating "I am light" 9 times. That also wards off all evil dark beings (no need of a priest throwing holy water, LOL). Divine light has many more effects actually. But be careful because too much light dazzles you and too much darkness leaves you groping. These days I use to call my internal dragon or some buddha to free energy from my own self in an intelligent way, to avoid becoming imbalanced. My path is still one of experimentation. I still don't know if defining myself as a Chaos Magician or a Buddhist, but do I really need labels?
Good grief.
