Again, we know that motion which has become latent can be brought back to manifestation. By hard work and practice certain motions of the body which are most dormant can be brought back under perfect control. Reasoning thus we find there is no impossibility, but, on the other hand. every probability that each part of the body can be brought under perfect control. This the Yogi does through Pranayama. Perhaps some of you have read that in Pranayama, when drawing in the breath, you must fill your whole body with Prana. In the English translations Prana is given as breath, and you are inclined to ask how that is to be done. The fault is with the translator. Every part of the body can be filled with Prana, this vital force, and when you are able to do that, you can control the whole body. All the sickness and misery felt in the body will be perfectly controlled; not only so, you will be able to control another's body. Everything is infectious in this world, good or bad. If your body be in a certain state of tension, it will have a tendency to produce the same tension in others. If you are strong and healthy, those that live near you will also have the tendency to become strong and healthy, but if you are sick and weak, those around you will have the tendency to become the same.
