The power of visualisation

[zenmaster]

I remember somewhere on the Ra writings that he described that in order to heal, we had to have basic anatomical understanding.

If the ailment is caused by an emotional imbalance or misunderstanding, the healing can be immediate by using the imagination. With that method, the mind symbolically describes the particular disposition of the body (through focus of will) and you just work with it to repair or balance. But as far as I know, this requires indigo ray function, just as Ra mentioned. For most people, this requires first "raising their vibrations" and crystals are helpful.
Others may be healed remotely, using the same method.
