What is the strongest prayer for healing?

Evil Karma is not punishment, neither is it fatality. 

It is the result of inharmony—a something wrong—a law broken that must be adjusted. 

And until such adjustment is made, more or less suffering must be experienced. 

It is like a splinter in a tender spot. 

The spot will fester until the splinter is removed, but would you think it wise to allow the spot to fester until—by the sloughing of the surrounding tissues—the splinter was eliminated? 

Or would a wise physician use his higher powers (his trained intelligence) to remove the splinter at once and allow the spot to heal? 

Again, a wheel has become flattened on one side and runs with great friction and jarring, throwing out of gear all parts of the engine. 

This, no doubt, is bad Karma from bad usage, but the engineer is fully justified in using his higher powers to have the defect remedied at once. 

Thus it is with The Healing Prayer—

Its earnest repetition, with an effort to grasp its real significance, arouses in the consciousness a realisation of what is wrong. 

You recognise the Divine Creative Force of Love—

The Christ-power—

The instant such a recognition is made, the splinter is removed, the defective machine repaired and atonement is made. 

For The Christ has spoken—

Go and sin no more.

THE HEALING PRAYER

O thou loving and helpful Master Jesus! 

Thou who gavest to thy disciples power to heal the sick!

I, recognising thee, and realising thy divine presence within me, 

Ask thee to lay thy hands upon me in healing love.

Cleanse me from all my sins, 

And by the divine power of omnipotent life, 

Drive out the atoms of inharmony and disease, 

And fill my body full to overflowing with life and love and purity.
