Love is the active ingredient in miracles. Everything which expresses from love is miraculous. This doesn't simply mean that "love just loves", it means love actually has a miraculous, miracle-working power to it. It is capable of healing absolutely anything.
With this in mind, a very simple healing approach is to give love.
1) Attempt to become ONE with another person in your mind. Imagine you are merging with them and occupying the same space as them. Be in their body. Join with them. Their mind is your mind. They are you.
2) Access love within your mind. If you need to remind yourself of love by remembering some moment in life where you felt strong love, that's ok. Ultimately you want to tune into God and Holy Spirit and feel their love. Love is the active ingredient so you must be able to feel it. Being able to feel God's love may take some time to develop depending on your degree of trust and openness etc.
3) Command that the person's sickness, as though a 'thing' in its own right, be fully healed right now. Address it directly as though talking to a person. Tell it what to do, like leave right now. Command that the area in question be fully healed right now. Realize that your command itself is not power, it is like a key that open a door for God to flow. Command and then let go and trust and expect God to flow.
4) Visualize Holy Spirit flooding the area with love. Visualize God Himself being in that exact location, radiating His Presence. You should aim to feel His love in that location. You should be able to also sense how His love is such a healing balm, so soft and refreshing and restorative, that its mere presence is miraculous and able to cure and heal anything.
In summary, and simplifying:
Tune into love and send love to the person and experience God's loving presence in the area that needs healing.
