     Throw the bottles and boxes of drugs out of your house. A new theory suggests that medicine

could be bad for your health, which should at least come as good news to people who cannot

afford to buy expensive medicine. This new theory argues that healing is at our fingertips: we can

be healthy by doing Yoga on a regular basis.

     Supporters of medical treatment argue that medicine should be trusted since it is effective and

scientifically proven. They say that there is no need for spiritual methods such as Yoga. These

waste our time, something which is quite precious in our material world. There is medicine that

can kill our pain, xrays that show us our bones or MRI that scans our brain for tumors ( 肿瘤) .

     We must admit that these methods are very effective in the examples that they provide. However,

there are some "everyday complaints" such as back pains, headaches, insomnia, which are treated

currently with medicine. When you have a headache, you take an Aspirin; when you cannot sleep,

you take Xanax without thinking of the side effects of these. When you use these pills for a long

period, you become addicted to them; you cannot sleep without them. We pay huge amounts of

money and become addicted instead of getting better. How about a safer and more economical

way of healing? When doing Yoga, you do not need anything except your energy so it is very

economical. Its popularity has spread particularly throughout America and Western Europe. In

quantum ( 量子) physics, energy is recognized as the fundamental substance ( 物质) which the

universe consists of. Yoga depends on the energy within our bodies. It is a simple and effective

way of restoring the energy flow. There are no side effects and it is scientifically explained.

     Opponents of alternative healing methods also claim that serious illnesses such as HIV/AIDS

and cancer cannot be treated without drugs. They think so because these patients spend the rest

of their lives in the hospital taking medicine. How can Yoga make these people healthy again? It is

very unfortunate that these patients have to live in the hospital losing their hair because of chemotherapy ( 化疗), losing weight because of the side effects of the medicine they take. Actually, it is common

knowledge that except when the cancer is recognized at an early stage, drugs also cannot treat AIDS

or cancer. Most of the medicines these patients use are to ease their pain and their sufferings. Instead

of drugs which are expensive and have many side effects, you can use your energy to overcome the

hardships of life, find an emotional balance, leave the stress of everyday life and let go of the everyday

worries. We should definitely start learning Yoga and avoid illnesses before it is too late.
