There are two levels on which you basically can operate, and this also relates to how you perform miracles.
The first level - "level 1" - is physical - this physical universe, which includes the physical body. On this level, the physical body directly interacts with other physical bodies through physical activities. So you might think that to perform healing at this level, you need to physically touch someone.
The second level - "level 2" - is non-physical - its the spiritual universe which includes the "spiritual body". On this level, the spiritual body interacts with other spiritual bodies through spiritual activities. The spiritual body doesn't particularly go around being physical or doing physical things or interacting physically. Interactions are mental.
Therefore, recognize that when you're attempting to perform healing miracles for people, whatever actions you perform with your body will NOT produce healing. And miracles do not COME FROM this level.
Also, if you attempt to direct your mind on the spiritual level towards the physical body of the other person, that also may not produce healing.
Instead, recognize that your mind on the mind-level needs to interact with - join with - the mind of the other person - at least their spiritual body - on the mental level, in order for it to produce changes there.
So while you're in your physical body, perhaps laying your hands on the sick or performing some physical action like holding out your hands etc, recognize that this alone will not produce miracles.
What needs to happen is a kind of 3-step process.
1. You be in your body but you reach up into your mind and access your mental powers.
2. Your mental body reaches out to the mental body of the other person and forgives and heals them and sees them as healed.
3. Their mental body translates the healing on the mental level back down into their physical body.
This seems sort of indirect to us on this level but it's really the only way that healing can seem to transfer from one physical person to another. You must access the level of mind where you can *actually* join with your brother, because you definitely CANNOT join with your brother on the physical level. Joining is oneness, and oneness brings healing.
Recently I was just about to lay my hands on my wife to do a healing and Holy Spirit stopped me. He was quite abrupt. It was because I was starting to be of the mindset that if I would take this physical action, somehow it would produce healing. He wanted to teach me that this is not the case. Bodies are not CAUSES, they are effects. And miracles are not coming from physical actions (but physical actions can express them).
When you start to believe that your physical-level self has something to do with healing, you are entering into a belief in magic. Magic is the belief that bodies have their own will, they have causal power, and they can make things happen. So now if you buy into this idea that you must approach someone physically and do something physical, you're actually turning the potential for a miracle into a sorry excuse of magical weakness.
I believe Holy Spirit is guiding me to recognize that our mind must access other minds on a mind level, to facilitate healing principles, and effectively this means even our own body is really nothing to do with the healing process. Healing may or may not flow through your body, but it is not required. Healing flows from Mind (God) to minds (Sons of God). The minds of the Sons of God then translate this and express it into the physical where they then demonstrate relief.
What this also means is that healing can for sure be accomplished remotely, purely in the mind, without any physical contact or proximity at all. So something has to happen within your awareness, inside your mind, in order to heal, and not just stand there touching someone and doing a bunch of stuff. Even if you are giving verbal commands, if you are of the mindset that just "saying the word" will do it, you are mistaken. The mind must believe and be involved, which the ego does not want.
The mind must be renewed and you must have moved your sense of identity away from the physical body level and into the spiritual level. That means letting go of ego and purifying your awareness and having a sense of identity that is anchored in the spiritual realm, in Holy Spirit, rather than in the physical. And part of that means learning to recognize that bodies are not real at all, they are just illusions, and that's why they CAN express different effects.
If you are not there yet, for sure you can temporarily shift your "self" away from the body and toward the spiritual mind, by using your imagination and visualizing healing taking place - perhaps asking Holy Spirit to help you - from your mental self to the mental self of others. You can see their spiritual "body", you can see it healing, and you can cast out sickness and dark thoughts. If the person will receive it and allow it, they'll also allow this to show up in their physical expression.
It's kind of like you need to hop in an elevator, go up to the next floor, walk across the corridor to another person who also came up to the next floor via another elevator, love them and heal them, and the let them go back down to the ground floor. And you can do all this at any time, even while you're in your body interacting with the person's physical body. Just remember it is your spiritual self/body that is joining with their spiritual self/body, and both of your physical bodies are just illusory effects.
