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 Reiki, Yoga, or Tai Chi. These waste our time, something which is quite precious in our material world. There is medicine that can kill our pain, x-rays that show us our fractured bones or MRI that scans our brain for tumors. We must admit that these methods are very effective in the examples that they provide. However, there are some "every day complaints" such as back pains, headaches, insomnia, which are treated currently with medicine. When we have a headache, we take an Aspirin, or Vermidon; when we cannot sleep, we take Xanax without thinking of the side effects. When we use these pills for a long period, we become addicted to them; we cannot sleep without them.
