Chapter 7 - Kriya Yoga 

Day 54 

When life will move through all these fires, it will emerge as gold. Unfortunately, you have not understood this principle. You do not even allow the fire to come up in you. When you have fever, you take paracetamol and suppress it. 

You just get rid of the symptoms of the problem. You do not attend to the root cause. It is not that you should not take medicines. You should take it the natural way. You should attend to the root cause of the problem and eliminate the bacteria, rather than just eliminate the symptoms or the fire in the system. Naturopathy and Ayurveda deal with this principle to keep alive the Bhootaagni. 

Your body had its own air-conditioning system. But, it you turn on the external air conditioner all the time, then you are destroying the self modulating system of the body. The air conditioner is kept switched on all the time in hot and tropical countries. There is no prana, or freshness in such an environment. 

When it is hot, you sweat and this cools you, just as you feel cool when there is a breeze. The body has its own air conditioning system. But, you need to get used to this from early in life. If you have been used to air conditioners from then, you may find it difficult to change. 

But nevertheless you can try. I have nothing against air conditioners but making sure that the fresh prana comes and your body temperature agrees with the environment will make a difference. Then, you gain the ability to be in a cold place without having to wear too many warm clothes. Or to be in a hot place and not feel suffocated.
