Three types of Sciences

In my experience, there are three kinds of sciences. The first type of Science is the "Science of matter". Science of matter can go as deep as atoms and molecules. The basis of this science is atomic structure and possible results of interactions/reactions between 2 or more atoms/molecules. Most modern day sciences are based on this basic "Science of Matter". For example a modern medical doctor prescribes medicines based on the reaction those atoms from chemicals will have with the atoms of cells within the body. This is the most tangible of the three sciences.

A little more subtle than the science of matter is "Science of Energy". How one feels at what time cannot be based on matter alone. There is a small amount of overlap between the "Science of Matter" and the "Science of Energy" - for example, if you eat a few pizza slices, you may feel your energy levels going down and you may feel sleepy. Or if you get yourself drugged, you may feel a change in your energy levels. But beyond that, there is not much of an overlap between these two sciences. Most meditators who have felt (even for a brief moment) that they are something more than the body, will be able to relate to this "Science of Energy". Many ancient medicinal sciences like the Chinese herbal medicine and Indian Homeopathy medicine are based on this Science of Energy. They determine the main energy pathways in the body and in case of any disease, the diagnosis is based on which energy pathway is blocked and not operating freely. Once that energy pathway is cleaned up, the body is naturally able to cure itself of the disease.

The third type of science is the "Science of Consciousness". This is the most subtle of the three sciences. It is your consciousness which actually manifests diseases. For example, someone who is constantly into "Victim Consciousness" (which means he constantly feels that the whole world is against him and he is always a victim) wants to prove to everyone that he is being troubled. That person may throughout the year develop ailments such as cold, cough, body aches and pains etc. How the consciousness of a person changes across a lifetime (and in fact multiple life-times) cannot be determined by the science of matter or the science of energy. Of course, there is a small influence of the science of energy - for example, the environment in which a person is brought up in, may have some influence on the consciousness. By pranayam, meditation and sudarshan kriya, this can be controlled and the consciousness made clean.

To my experience, dealing at the level of consciousness can make life much more easy, compared to dealing at the level of matter or energy. Dealing at the level of matter may have a lot of side-effects, which reduce while dealing at the level of energies and pretty much disappear while dealing at the level of consciousness. The "power of prayer", "faith healing" etc works at the level of consciousness.

A strong consciousness can influence the environment, while a weak consciousness can get influenced by the environment. Every human body has a strong defense mechanism which can deal with any disease in its environment. This process can be significantly more powerful, if the consciousness of the person also genuinely wants to do it - and the consciousness is pure and free from all negative emotions such as guilt, victimness etc. Sudarshan Kriya, pranayam etc helps the consciousness to be free from all these negativity, so that the energy and the body of the person can be much more healthier and if the person wants, he/she can help build a much better and beautiful world.
