Electric current does not have its own intelligence. If you fix a bulb in the socket, it will glow. If you put your hand in the socket, it will give you an electric shock! But the energy in your body is not like that. It is an intelligent, healing energy. Your body has a natural self-healing energy. You can see it at work when you see a cut or a wound healing itself even without any intervention on your part. There is an automatic body intelligence which is constantly rejuvenating and even replacing the cells in your entire body. If some part of the body is damaged you have enough intelligence inside to replace the damaged cells. But when the ego or mind interferes, this natural process is interrupted.
Constantly our body repairs itself and cells replace themselves.
You might ask, ‘Then why does the same disease occur again in my body? If my body is again and again replacing itself, rejuvenating itself, then why do I carry the same disease?’ Because you strongly believe that the disease is continuing! You carry the same mental setup that strongly believes that you are not well. This is what stops the self-healing from happening in your body. All you need to do is just trust the automatic intelligence which is in you and relax.
Energy is intelligence. Your being is intelligence. The problem is, you never trust that your being is intelligent. You weigh yourself only with your weakest link and you are not your weakest link. Be aware, you are something more than your weakest link. The strength of a chain can be measured based on the weakest link but the strength of your being cannot be measured this way because you are something more than what you think you are. Actually your body has the capacity to heal every disease, physical or mental, however complex it might be. The secret is to use the lost science of self-healing. This is what the science of Nithya Spiritual Healing is all about. It is a process of connecting the intelligence of the person to the cosmic energy, which is pure intelligence, through an initiated healer.
