A small story:
When Queen Draupadi was being disrobed in public in the court of the Kauravas, she started crying out to Lord Krishna for help. Again and again, she cried out, Krishna, help me! Krishna, help me!
But at the same time, she was clutching her saree (clothes) with both hands. Finally, when she saw that she was on the verge of being totally undressed, she just threw up both her hands and called out, Krishna, help me! This time, her prayer was answered instantaneously. Her saree reappeared miraculously and she was saved.
Later, Draupadi complained to Krishna, My Lord, why did you take so long to come and save me? Did you not see that I was alone and helpless?
Krishna replied, Draupadi, you were calling me, but at the same time you were trying to protect yourself. Till the very end, you thought that you could manage by yourself. But at the end, when I saw you totally open, I had to come. I had to appear and take care of you.
This is what we all do in our life.
We say that we have faith, but actually Existence or God is only our Plan B! God or the universal intelligence is our last resort.
Understand, the fish is always in the river, whether it chooses to swim upstream and struggle, or just floats peacefully with the current. The Existential energy is always available. Whether you want to tune yourself to it or not is upto you. It is purely subjective.
Precisely because it is such a subjective experience, the causes and effects of energy healing and other such 'miracles' cannot be always correlated and quantified.
That is why, in spite of cases of healing, methods like spiritual healing are not part of mainstream healthcare even today.
In the medical field, if you can show some improvement after using a particular drug, that drug is approved as a medicine.
Definitely, some patients experience relief with healing. So ideally, placebo effect should have its rightful place in physical and mental healing.
But unlike allopathic drugs, it needs the co-operation of the patient as well. The click has to happen.
Unless the human consciousness rises above logic, it cannot comprehend the working of the cosmic law. Until then, some part of the population will continue to dismiss spiritual healing and wish-fulfilment as cheap miracles or auto-hypnosis!
